Exploring physical and chemical properties in new multifunctional indium-, bismuth-, and zinc-based 1D and 2D coordination polymers

Abstract

Main group elements coordination polymers (MGE-CPs) are important compounds for the development of multifunctional materials. However, studies regarding to structural, optical, catalitic, mechanical or antibacterial properties have strikingly less reported. In this work, an exhaustive study of a set of crystalline MGE-CPs obtained from bismuth and indium metals, iminodiacetate, 1,2,4,5-benzenetetracarboxylate, and 2,2’-bipyridine as building blocks is presented. An in-deep topological analysis of the networks was carried out. Besides, nanoindentation studies were performed on two representative low dimensional compounds in order to find the relationships between their structural features and the intrinsic mechanical properties (hardness and elasticity). The solid state photoluminescence (SSPL) properties were also studied in terms of excitation, emission, lifetimes values and CIE chromaticites. Moreover, the heterogeneous catalytic activities of the compounds were evaluated in the cyanosilylation reaction using a set of carbonylic substrates under solvent-free conditions. Finally, the inhibitory effect of the Bi-CPs on the growth of microorganisms such as Escherichia coli, Salmonella enterica serovar Typhimurium and Pseudomonas aeruginosa, which are associated with relevant infectious diseases, is reported.
