The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Two nonporous MOFs with uncoordinated carboxylate groups: Fillers for enhancing the proton conductivities of nafion membrane, the main research direction is nickel cadmium bipyridine isophthalate MOF preparation crystal structure; thermal stability nickel cadmium bipyridine isophthalate MOF; proton conductivity nickel cadmium bipyridine isophthalate MOF composite membrane.SDS of cas: 1762-34-1.
Two nonporous MOFs [Ni(L)0.5 (Mbpy)(H2O)2]2 (1) and [Cd(H2L)(Mbpy)]n (2) (H4L = 5,5′-(butane-1,4-diylbis (oxy))diisophthalic acid, Mbpy = 5,5′-dimethyl-2,2′-bipyridine) were obtained through hydrothermal reactions under different pH values reaction condition. Structure analyses reveal that there are uncoordinated deprotonated and protonated carboxylate groups in compounds 1 and 2, resp., which are confirmed by IR spectra. The XRD and TG studies indicate that both of compounds exhibit good water and thermal stability. The proton conductivities of the Nafion membrane doped by compounds 1 and 2 were studied. Compound 2 can enhance the proton conductivity of the composite membrane ∼29% higher than that of pure Nafion. The water uptakes of 1/Nafion and 2/Nafion composite membrane are similar and slightly higher than that of pure Nafion membrane. The apparently high proton conductivity of 2/Nafion membrane should be attributed to the high proton d. of 2 framework, which is resulted by the protonated uncoordinated carboxylate acid groups.
