In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Addressing Multiple Ions Using Single Optical Probe: Multi-Color Response via Mutually Independent Sensing Pathways, published in 2020, which mentions a compound: 1762-34-1, mainly applied to multiple ion single optical probe sensing emission quenching, Recommanded Product: 1762-34-1.

Multiresponsive smart optical probe based on p-phenylene vinylene backbone is designed for simultaneous sensing of multiple ions, such as Cu2+, Zn2+ and F- at pH 7.4. A rapid color change from colorless to deep yellow is observed upon addition of both Cu2+ and Zn2+ ion. However, under long UV lamp, the green-colored emission of the probe is specifically quenched in the presence of Cu2+, while Zn2+ induces change in the emission color from green to yellow. On the contrary, F-, unlike Cu2+ and Zn2+, does not render any change in visible color, however, an emission quenching, similar to that of Cu2+ addition, was noticed. The binding of metal ions to the central bipyridine core diminishes the ′conformational flexibility′ and facilitates ′ligand to metal ion′ charge transfer. On the contrary, addition of fluoride triggers the cleavage of silyl ether groups and results in the photo-induced electron transfer from free hydroxyl groups to the core aromatic unit. Thus, we can detect as well as discriminate these three ions (Cu2+, Zn2+ and F-) simultaneously by comparing the resp. output signals. Further, a sustainable strategy has been developed for on-site detection of toxic ions using reusable, low-cost paper strips.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called High sensitivity and selectivity of aminoantipyrine schiff base for recognition of Fe2+, published in 2019, which mentions a compound: 1762-34-1, mainly applied to chemosensor aminoantipyrine schiff base iron, Product Details of 1762-34-1.

An aminoantipyrine based chemosensor, (E)-1,5-dimethyl-4-((2-(4-methylpyridin-2-yl)pyridin-4-yl)methyleneamino)-2-phenyl-1,2-dihydropyrazol-3-one(L), derived from 4-aminoantipyrine and 2-(4-methylpyridin-2-yl) isonicotinaldehyde, was synthesized and the optical and metal sensing properties were investigated. The chemosensor L showed a selective colorimetric sensing ability for Fe2+ by changing colors from pale yellow to deep red in water-ethanol (9:1, V/V) medium, which facilitates the ‘naked-eye’ recognition of Fe2+ from other examined metal ions. The complex stoichiometry of Fe2+ to L(1:3,[FeL3]2+) was obtained by Job’s method. The association constant was determined to be 3.70×1021 L3·mol-3. The present results indicate that the chemosensor L could be used as a selective, sensitive colorimetric sensor for Fe2+.

Two novel binuclear lanthanide complexes, [Ln(3-Cl-4-MOBA)3(5,5′-DM-2,2′-bipy)]2(5,5′-DM-2,2′-bipy) (Ln=Eu(1), Gd(2)), (3-Cl-4-MOBA=3-chloro-4-methoxybenzoate; 5,5′-DM-2,2′-bipy=5,5′-dimethy-2,2′-bipyridine) have been successfully synthesized under hydrothermal conditions. The complexes are characterized by single-crystal X-ray diffraction and elemental anal. Complexes 1 and 2 are isomorphous, and each metal center is eight-coordinated with a distorted square-antiprism coordination geometry. The binuclear units are assembled into 1D, 2D and 3D supramol. structures by weak hydrogen bonds (C-H···O and C-H···Cl) and π-π stacking interactions. Thermal behavior of the complexes 1 and 2 was determined by TG/DSC-FTIR techniques. Heat capacities of the complexes are measured by a DSC instrument in the temperature range of 283.15-393.15K. Based on the heat capacities date, the thermodn. functions (HT-H298.15K) and (ST-S298.15K) were obtained. The activation energy E values of the first decomposition stage for complexes 1 and 2 were calculated by integral iso-conversional nonlinear (NL-INT) method. The fluorescence spectra and lifetime of complex 1 (Eu3+ ion) were studied in depth.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,5′-Dimethyl-2,2′-bipyridine(SMILESS: CC1=CN=C(C=C1)C1=NC=C(C)C=C1,cas:1762-34-1) is researched.Recommanded Product: 1671-88-1. The article 《Molecular engineering towards tunable morphology of metal-organic complex microcrystals for efficient and multicolor electrochemiluminescence》 in relation to this compound, is published in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices. Let’s take a look at the latest research on this compound (cas:1762-34-1).

Electrochemiluminescence (ECL) of crystalline materials has recently attracted increasing attention due to their unique characteristics and applications, such as crystallization-induced emission, active waveguiding, and biosensing. Tris(2,2′-bipyridine)ruthenium(II), [Ru(bpy)3]2+, a classical metal-organic complex for ECL studies, has been fully investigated in solution as well as its derivatives However, the dependence of ECL properties on the mol. structure and crystal morphol. of these complexes has not been illustrated, partially due to the difficulty in the controlled crystal growth. Here, we adopt a facile mol. engineering strategy to obtain microcrystals of [Ru(bpy)3]2+ derivatives with well-defined morphol. (rods, wires, or polyhedrons) and varied phosphorescence emission colors (yellow, orange, and red) by simply changing the position and number of Me substituents on the bipyridine ligands. The packing modes of mols. influenced by Me groups play a vital role in crystal growth based on attachment energy anal. The obtained microcrystals could act as ECL luminophores when modified on glassy carbon electrode surfaces. Those with one-dimensional (1D) morphol. generally show superior ECL efficiency and stability to three-dimensional (3D) shaped microcrystals. ECL biosensors made of stable 1D microcrystals show reliable and sensitive responses to hydroxyproline, demonstrating their capacity in recyclable detections. This work demonstrates the great potential of mol. engineering in controlling the morphol., emission colors, and ECL properties of mol. crystals, paving the way for the development of high-performance ECL biosensing and optoelectronic devices.

Safety of 5,5′-Dimethyl-2,2′-bipyridine. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Exploiting the versatility of pyridyl ligands for the preparation of diorganotin (IV) adducts: spectral, crystallographic and Hirshfeld surface analysis studies. Author is Momeni, Badri Z.; Fathi, Nastaran; Abbasi, Reyhaneh; Janczak, Jan.

Diorganotin (IV) complexes SnR2X2 (R = Me, Ph; X = Cl, NCS) form a series of versatile complexes when react with bidentate substituted pyridyl ligands. The reaction of dimethyltin dichloride with 5,5′-dimethyl-2,2′-bipyridine (5,5′-Me2bpy) resulted in the formation of [SnMe2Cl2(5,5′-Me2bpy)] (1). Moreover, the reaction of SnMe2(NSC)2 with 4,4′-di-tert-butyl-2,2′-bipyridine (bu2bpy), 1,10-phenanthroline (phen) and 4,7-diphenyl-1,10-phenanthroline (bphen) affords the hexa-coordinated complexes [SnMe2(NCS)2(bu2bpy)] (2), [SnMe2(NCS)2(phen)] (3) and [SnMe2(NCS)2(bphen)] (4), resp. The resulting complexes have been characterized using elemental anal., IR, multinuclear NMR (1H, 13C, 119Sn) and DEPT-135° NMR spectroscopy. On the other hand, the reaction of diphenyltin dichloride with 2,2′-biquinoline (biq) and 4,7-phenantroline (4,7-phen) led to the formation of polymeric complexes of [SnPh2Cl2(4,7-phen)]n (5) and [SnPh2Cl2(biq)]n (6). The NMR spectra, however, reveal the ligand lability in solution and suggest a coordination number of 5. The X-ray crystal structures of complexes [SnMe2Cl2(5,5′-Me2bpy)] (1), [SnMe2(NCS)2(bu2bpy)] (2) and [SnMe2(NCS)2(bphen)] (4) have been determined which reveal that the geometry around the tin atom is distorted octahedral with trans-[SnMe2] configuration. Interestingly, the crystal structure of (H2biq)2[SnPh2Cl4]•2CHCl3 (7) was characterized by X-ray crystallog. from a chloroform solution of [SnPh2Cl2(biq)]n (6) indicating the formation of doubly protonated [H2biq]+ and [Ph2SnCl4]2- which are stabilized by a network of hydrogen bonds with a feature of trans-[SnPh2]. The 3D Hirshfeld surface anal. and 2D fingerprint maps were used for quant. mapping out of the intermol. interactions for 1, 2, 4 and 7 which show the presence of π-π and hydrogen bonding interactions which are associated between donor and acceptor atoms (N, S, Cl) in the solid state.

HPLC of Formula: 1762-34-1. The reaction of aromatic heterocyclic molecules with protons is called protonation.

The size of N-N ligand and its substituents modulate the compound electronic features and influence their antiproliferative efficiency against Entamoeba histolytica, 56dmphen derivative, shows the biggest molar volume and presents a powerful amoebicidal activity (IC50 = 1.2μM), being seven times more effective than the first-line drug for human amoebiasis metronidazole. Also, increases the reactive oxygen species concentration within the trophozoites. This could be the trigger of the E. histolytica growth inhibition. The antiparasitic effect is described using NiII electron d., molar volume, estimated by DFT, as well as the exptl. redox potential and diffusion coefficients In general, amoebicidal efficiency is directly proportional to the increment of the molar volume and decreases when the redox potential becomes more pos.

Formula: C12H12N2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Multimode Self-Oscillating Vesicle Transformers. Author is Shao, Qing; Zhang, Shaodong; Hu, Zhen; Zhou, Yongfeng.

Engineering synthetic materials that mimic the complex rhythmic oscillatory behavior of living cells is a fundamental challenge in science and technol. Up to now, the reported synthetic model system still cannot compete with nature in oscillatory modes and amplitudes. Presented here is a novel alternating copolymer vesicle that exhibits drastic and multimode shape oscillations in real time, which are controlled by polymer concentrations and driven by the Belousov-Zhabotinsky oscillatory reaction, including swelling/deswelling, twisting/detwisting, stretching/shrinking, fusion/fission, and multiple division. Some of them, especially the fission oscillation, have not been observed before. In addition, the oscillation magnitude with regard to diameter is much larger than that of previously reported self-oscillating vesicles. Such a self-oscillating vesicle transformer would extend the complexity and capacity of membrane deformations in synthetic systems, approaching those of natural cells.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Synthesis and Acid-Responsive Properties of a Highly Porous Vinylene-Linked Covalent Organic Framework, the main research direction is acid responsive porous vinylene covalent organic framework; Hill equation; acid response; acidochromic; covalent organic framework; fluorescence; gas sensor.Reference of 5,5′-Dimethyl-2,2′-bipyridine.

The recently emerging vinylene-linked covalent organic frameworks (VCOFs) stand out from other COFs with exceptional chem. stability and favorable light-emitting properties, promising sensing applications for acids/bases or in strong acidic/basic conditions. Here we systematically investigated the reversible color and fluorescent response of a VCOF functionalized with pyridyl groups to acids/pH. The COF was synthesized with a record surface area for VCOFs and shows reversible hydrochromic and acidochromic behaviors and concomitant fluorescence quenching. The mechanisms were probed with systematical exptl. comparison with relevant COFs and model mols. in combination with orbital anal. The response is related to significant electronic changes in the ground and photoexcited states as a result of protonation or hydrogen bonding at pyridyl sites. The COF in aqueous dispersion displays a reversible fluorescence transition with pH change, which follows the Hill equation for multisite protonation. The COF-modified test paper shows immediate and remarkable color change and fluorescence turn-off/on when alternately exposed to HCl and NH3 gases. The work illustrates the great potential of developing highly robust sensory COFs through the vinylene approach.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Asahara, Masahiro; Kurimoto, Haruhiko; Nakamizu, Masato; Hattori, Shingo; Shinozaki, Kazuteru researched the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ).Recommanded Product: 5,5′-Dimethyl-2,2′-bipyridine.They published the article 《H/D solvent isotope effects on the photoracemization reaction of enantiomeric the tris(2,2′-bipyridine)ruthenium(II) complex and its analogues》 about this compound( cas:1762-34-1 ) in Physical Chemistry Chemical Physics. Keywords: preparation ruthenium bipyridine phenanthroline complex; solvent isotope effect ruthenium bipyridine phenanthroline complex; photoracemization reaction ruthenium bipyridine phenanthroline complex. We’ll tell you more about this compound (cas:1762-34-1).

This work assessed solvent isotope effects on the photoracemization rate and emission lifetime for [Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) in water. An anal. of the effects of temperature on photoracemization rate and emission lifetime demonstrated that the transition from one enantiomer to the other is unaffected by the isotopic composition of the solvent. Also deactivation from the metal-to-ligand charge-transfer (3MLCT) excited state to the ground state is responsible for the solvent isotope effect on the photoracemization rate. The photoracemization reaction proceeds via a bond-breaking mechanism. In this process, a five-coordinated species produced through breaking of the Ru-N bond in the 3d-d* state undergoes a structural change to produce an achiral five-coordinated species. An anal. of the effect of temperature on emission lifetime, excluding the activation to the 3d-d* state that leads to the structural change, showed that the solvent isotopic composition affects deactivation from the 4th MLCT state.

Various substrates and functional groups were tolerated. The practical applications of this reaction were further demonstrated by enlarged gram-scale and various derivations for complex heterocycles. Primary mechanistic studies suggested the involvement of cobalt-hydride mediated hydrogen atom transfer (HAT) process.
