摘要

将不同的功能集成在一种材料中，可以减少设备的体积、响应时间和价格。聚酰亚胺(PIs)具有优异的柔性力学、热稳定性和透明性能，是最佳的候选材料。本文以一种新型功能化三芳胺为原料，设计并合成了一系列用于电致变色器件的多功能柔性pi。该pi在EC中具有良好的应用前景，效率为205 cm2 C−1,ON/OFF比为3.7 × 104的存储器件，以及极限为0.07 V的光电探测器。此外，PI-3 (PI-3的简称，由4,4 ' -(六氟异丙基)二苯二酸酐制成)的柔性EC器件保持了良好的稳定性，即使循环2000次也不降低光学对比度。

Multifunctional polyimides containing triarylamine for electrochromic flexible device, photodetector and resistance memory device

Integrating different functions in one material will decrease the volume, responding time, and price of device. Polyimides (PIs) are the optimal candidates because of excellent flexible mechanics, thermal stability, and transparent properties. In this work, a series of multifunctional flexible PIs were designed and synthesized from a novel functional triarylamine for electrochromic (EC) device. The PIs show promising application in EC with the efficiency of 205 cm2 C−1, memory devices with the ON/OFF ratio of 3.7 × 104, and photodetectors with a limit being of 0.07 V. Furthermore, the flexible EC device of PI-3 (short for PI 3 made of 4,4′-(hexafluoroisopropylidene) diphthalic anhydride) keeps excellent stability, and the optical contrast does not decrease even after 2000 cycles.
