Main group element coordination polymers (MGE-CPs) are important compounds for the development of multifunctional materials. However, there has been a shortage of studies regarding their structural, optical, catalytic, mechanical, and antibacterial properties. This work presents an exhaustive study of a set of crystalline MGE-CPs obtained from bismuth and indium metals and iminodiacetate, 1,2,4,5-benzenetetracarboxylate, and 2,2'-bipyridine as building blocks. An in-depth topological analysis of the networks was carried out. Additionally, nanoindentation studies were performed on two representative low-dimensional compounds in order to find the relationships between their structural features and their 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 with 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.
主族元素配位聚合物(MGE-CPs)是开发多功能材料的重要化合物。然而,关于它们的结构、光学、催化、机械和抗菌性能的研究一直不足。这项工作对一组由铋和铟金属以及亚氨基二乙酸、1,2,4,5-苯四羧酸和2,2'-联吡啶作为结构单元得到的结晶MGE-CPs进行了详尽研究。对这些网络进行了深入的拓扑分析。此外,对两种代表性的低维化合物进行了纳米压痕研究,以找出它们的结构特征与其固有机械性能(硬度和弹性)之间的关系。还从激发、发射、寿命值和CIE色度方面研究了固态光致发光(SSPL)性能。此外,在无溶剂条件下,使用一组羰基底物通过氰基硅烷化反应评估了这些化合物的多相催化活性。最后,报道了Bi-CPs对与相关传染病有关的微生物如大肠杆菌、鼠伤寒沙门氏菌和铜绿假单胞菌生长的抑制作用。
