Abstract

The current study describes the synthesis and complete characterization of three new copper coordination polymers, namely {[Cu₂(tyr)₂(Him)₃(Cl)₂(H₂O)₂].H₂O}_n 1, {[Cu₂(bdc)₂(Him)₃(H₂O)₄].H₂O}_n 2, and {[Cu(btec)(Him)₂].3H₂O}_n 3, where L-tyr = L-tyrosine, H₂bdc = terephthalic acid, H₄btec = pyromellitic acid, and Him = imidazole. They were characterized using various analytical techniques such as elemental analysis, FT-IR, UV–Vis, magnetic measurements, molar conductance, MM2 theoretical calculations, TG/DTA, and XRPD. Additionally, the catalytic activity of the complexes toward H₂O₂ decomposition was evaluated as well as their biological activity was tested against bacteria and fungi. The complexes exhibit an octahedral geometry around the copper centers. Thermogravimetric analysis confirmed the thermal stability of the complexes and their proposed structures. The results of the properties, including magnetism, activation energy (E*), nanoparticle sizes, catalytic activity and biological activity of these complexes were computed and discussed. The functional groups, hydrogen bonding, and copper ions significantly influenced the structures, physical properties and biological activity. The findings suggest that complex 1 is a promising candidate as a catalyst and medical transport, while complexes 2 and 3 are promising candidates as porous materials.

三种新型纳米超分子咪唑-羧基铜（II）配位聚合物的快速合成

本研究描述了三种新型铜配位聚合物{[Cu2(tyr)2(Him)3(Cl)2(H2O)2]的合成和完整表征。H2O}n 1, {[Cu2(bdc)2(Him)3(H2O)4]。H2O} n2和{[Cu(btec)(Him)2]。3H2O}n 3，其中L-tyr = l -酪氨酸，H2bdc =对苯二甲酸，H4btec =苯二甲酸，Him =咪唑。使用元素分析、FT-IR、UV-Vis、磁测量、摩尔电导、MM2理论计算、TG/DTA和XRPD等各种分析技术对它们进行了表征。此外，还评价了配合物对H2O2分解的催化活性以及对细菌和真菌的生物活性。配合物在铜中心周围呈八面体结构。热重分析证实了配合物及其结构的热稳定性。计算并讨论了这些配合物的磁性、活化能（E*）、纳米颗粒大小、催化活性和生物活性等性能。官能团、氢键和铜离子对其结构、物理性质和生物活性有显著影响。研究结果表明，配合物1是一种很有希望作为催化剂和医疗运输的候选者，而配合物2和3是一种很有希望作为多孔材料的候选者。
