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.Santoro, Antonio; Holub, Jan; Fik-Jaskolka, Marta A.; Vantomme, Ghislaine; Lehn, Jean-Marie researched the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ).Recommanded Product: 1762-34-1.They published the article 《Dynamic Helicates Self-Assembly from Homo- and Heterotopic Dynamic Covalent Ligand Strands》 about this compound( cas:1762-34-1 ) in Chemistry – A European Journal. Keywords: transition metal schiff base helicate complex preparation self assembly; crystal structure transition metal schiff base helicate; double-helical structures; dynamic covalent chemistry; metallo-supramolecular structures; programmed self-assembly. We’ll tell you more about this compound (cas:1762-34-1).
The understanding and the application of reversible covalent reactions and coordination chem. together with the proper design of the mol. frameworks, allow to achieve not only well-defined output architectures but also different grades of complex behavior. In this work, the dynamic nature of the helical systems offers an addnl. level of complexity by combining self-sorting on two levels: (1) the build-up of the ligand strand constituents from their components through dynamic covalent chem.; (2) the assembly of the helicates from the ligands and the metal cations through dynamic metallo-supramol. chem. The information encoded in the ligands constituent mol. was read differently (and accurately at the same time) by metal cations that varied in the coordination algorithms. It enabled the selective formation of a specific type of helicates from a wide library of helicates formed by the possible combination of subcomponents. Ligands containing dynamic tridentate and/or bidentate binding motifs in the same strand were studied to explore the helicates self-assembly with appropriate metal cations.
