摘要

以2-（3-叔丁基-2-羟基-5-甲氧基苄胺）乙酸（H3L）为胶凝剂合成了铜金属水凝胶。利用流变学、基质辅助激光解吸电离飞行时间（MALDI-TOF）质谱、FTIR、场发射扫描电子显微镜（FESEM）、高分辨率透射电子显微镜（HRTEM）、原子力显微镜（AFM）、x射线光电子能谱（XPS）、粉末x射线衍射（PXRD）和热重分析（TGA）对水凝胶进行了表征。研究了水凝胶作为比格内利缩合反应的多相、可重复使用催化剂的效果。我们还研究了水凝胶对革兰氏阳性菌和革兰氏阴性菌的抗菌活性。

A Multi-Functional Copper Metallogel as a Heterogeneous Reusable Catalyst for Biginelli Condensation and Antimicrobial Activity

A copper metallohydrogel has been synthesised using the gelator 2-(3-tert-butyl-2-hydroxy-5-methoxybenzylamino) acetic acid (H3L). The hydrogel was characterised using rheology, Matrix Assisted Laser Desorption Ionisation-Time of Flight (MALDI-TOF) mass spectrometry, FTIR, Field Emission Scanning Electron Microscopy (FESEM), High Resolution Transmission Electron Microscopy (HRTEM), Atomic Force Microscopy (AFM), X-ray Photoelectron Spectroscopy (XPS), Powder X-ray Diffraction (PXRD), and Thermo Gravimetric Analysis (TGA). The efficacy of the hydrogel as a heterogeneous, reusable catalyst for the Bignelli condensation has been investigated. We have also investigated the hydrogel's antimicrobial activity against both Gram-positive and Gram-negative bacteria.
