偶氮苯二茂铁棒状衍生物的合成、自组装、光物理及离子识别性能研究

Synthesis, self-assembly, photophysical and ion recognition properties of rod-shaped azobenzene ferrocene derivatives

摘要: 以Click反应作为关键步骤合成了偶氮苯二茂铁棒状衍生物Azo-Fc-m，通过POM、DSC、SEM及UV-vis、DFT等手段研究了化合物的自组装性质和光物理性质. 研究表明该类化合物能在溶液中组装成三维网络的有机凝胶，凝胶对光、热、力均有可逆的响应性；化合物具有可逆的光致异构化效应；氧化还原活性较弱. 化合物对Ag⁺离子具有专一识别性，有望作为识别Ag⁺的化学传感器材料.

Abstract: Rod-shaped azobenzene ferrocene derivative Azo-Fc-m were synthesized by Click reaction as the key step. The self-assembly properties and photophysical properties of the compounds were studied by POM, DSC, SEM, UV-vis, DFT etc. These compounds can assemble into organogel in solution with three-dimensional network morphologies. The gel has reversible response to light, heat and pressure. These compounds showed a reversible photoisomerization effect and can be used as a chemical sensor towards Ag⁺.
