The proton conductivities of two silver‐thiophene‐2‐carboxylate coordination polymer and the relationship between the dimensionality and properity

Abstract

Two 1D tpa complexes [Ag(tpa)(2-apy)] n (1) and {[Ag(3-apy)]·(tpa)·(H 2 O)} n (2) have been obtained from higher dimensional silver complex reaction systems and characterized. The complexes of 1 and 2 exhibit superprotonic conductivities with 3.27 × 10 −2 S·cm −1 and 2.25 × 10 −2 S·cm −1 respectively, in the same order of magnitude with that of the 1D 2,5-tpa complex. The structures and topological analyses show the relative positions of substituents in neutral ligands affect the existence modes of tpa ligands, influencing the topological results and distributions of proton conduction sites, which do not affect the proton conductivities of the complexes dramatically. Instead, the dimensionalities of the complexes are closely related to the proton conductivities, indicating that in high humidity, abundant hydrogen-bond networks are formed in pores and between main frameworks of the proton conductive compounds and influence the performance.

Halide-Salt-Free Synthesis of Silver Nanowires with High Yield and Purity for Transparent Conductive Films

“…40,41 Its position confirms a binding of carboxylate oxygens to silver. 42,43 However, the 1,2-PG heated at a temperature of 393 K in a closed reaction vessel did not show the characteristic peak. This proves that Ag + was the main oxidant in the 1,2-PG oxidation path.…”

Structural regulation of Co-based coordination polymers by adjusting solvent polarity toward electrocatalytic hydrogen evolution performance

“…It is beneficial for us to understand and better master the application of MOFs in electrocatalysis by exploring the differences in electrocatalytic performance caused by different dimensions due to different coordination modes. [35][36][37] The main reasons why we chose thiophene dicarboxylic acid as the organic ligand are its low price and that the introduction of sulfur into the coordination polymers may improve the electrocatalytic performance. The crystal structures of the three isomers were analyzed by single-crystal X-ray diffraction.…”
