A multi-responsiveness supramolecular metal-organic gel (MOG) has been prepared by using silver (I) nitrate and a simple ligand (L17) based on a biscarboxyl-functionalised benzimidazole derivative. The MOG that displays the formation of well-developed nanofibrillar networks composed of intertwined fibres was characterised by using field emission scanning electron microscopy (FESEM), Fourier transform
通过使用硝酸银 (I) 和基于双羧基官能化苯并咪唑衍生物的简单配体 (L17) 制备了多响应超分子金属有机凝胶 (MOG)。使用场发射扫描电子显微镜 (FESEM)、傅里叶变换红外 (FT-IR) 光谱和粉末 X 射线衍射 (XRD) 技术对显示由交织纤维组成的发达纳米纤丝网络形成的 MOG 进行表征。FT-IR 光谱和 XRD 表明超分子 MOG 是通过配体和 Ag+ 的有效配位形成的。该 MOG 揭示了由温度和 pH 变化以及通过添加 NH4OH、乙二胺四乙酸和 Na2S 引起的显着的可逆溶胶-凝胶转变。此外,MOG 还显示出良好的染料吸附能力。
