我们展示了一种使用聚二乙炔 (PDA) 和金属离子的共组装体对有机溶剂进行比色区分的简单且低成本的方法。该共组装体是通过两亲性 10,12-tricosa 二炔酸与不同金属离子（Zn2+、Cu2+、Ni2+、Ca2+）的自组装和随后的光聚合制备的。不同的金属离子与聚(10,12-三十二二炔酸)侧链上的羧基发生不同的相互作用，从而影响PDA/金属离子共组装体的刺激响应性。结果，具有不同金属离子的PDA/金属离子共组装体表现出不同的溶剂化显色性。基于这一特性，联合组件被用作传感器来区分有机溶剂。
We demonstrate an easy and low-cost approach for the colorimetric differentiation of organic solvents using co-assemblies of polydiacetylenes (PDAs) and metal ions. The co-assemblies were prepared by the self-assembly of amphiphilic 10,12-tricosa diynoic acid with different metal ions (Zn2+, Cu2+, Ni2+, Ca2+) and subsequent photopolymerization. Different metal ions underwent different interactions with the carboxyl groups on the side chains of poly(10,12-tricosa diynoic acid), which influenced the stimuli-responsiveness of the PDA/metal ion co-assemblies. As a result, the PDA/metal ion co-assemblies with different metal ions showed different solvatochromism. Based on this property, the co-assemblies were used as sensors to differentiate organic solvents.
