In this work, a series of multifunctional polyurethane (PU) materials containing three kinds of different triarylamine (TAA) units was prepared. These polymers show good solubility in common organic solvents and excellent thermal stability under a N2 atmosphere. The PU films show reversible color changes with high contrast ratios and electrochromic stability. Moreover, they have good memory storage performance. The ON/OFF current ratio is about two orders of magnitude. Meanwhile, they can be used as detectors for 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitrophenol (TNP). The polymer solutions rapidly exhibit fluorescence-quenching phenomena when exposed to trace amounts of TNT and TNP. The PU films also have mechanical properties that make them suitable for use in stretchable devices.

由不同的三芳基胺单元合成的多功能聚氨酯,具有电致变色,光生成,存储器存储和传感特性†
在这项工作中,制备了包含三种不同的三芳基胺(TAA)单元的一系列多功能聚氨酯(PU)材料。这些聚合物在普通有机溶剂中显示出良好的溶解性,并在N 2气氛下表现出出色的热稳定性。PU膜具有高对比度和电致变色稳定性,显示出可逆的颜色变化。而且,它们具有良好的内存存储性能。开/关电流比约为两个数量级。同时,它们可用作2,4,6-三硝基甲苯(TNT)和2,4,6-三硝基苯酚(TNP)的检测器。当暴露于痕量的TNT和TNP时,聚合物溶液迅速显示出荧光猝灭现象。PU膜还具有使其适用于可拉伸设备的机械性能。
