Abstract

The development of smart materials with reversible thermochromic properties is of great importance in the fields of sensors, displays and anticounterfeitings. In this article, a diacetylene monomer (AQDA) containing aminoquinoline as a head group was synthesized. Together with fluorescein-substituted diacetylene (FDA) and 10,12-pentacosadiynoic acid (PCDA), hybrid PDA vesicles were obtained through self-assembly and topochemical polymerization process. The hybrid PDA vesicles (FDA, AQDA and PCDA with molar ratio of 7:2:1) display an partially reversible green-to-orange red colorimetric change in a wider temperature range from 20 to 100 °C focusing on the stronger hydrogen bonding and aromatic interactions. This work may provide fundamental understanding of the mechanism and strategies for the design of reversible thermochromic PDA materials.

Graphical Abstract

A PDA derivative aminoquinoline-substituted polydiacetylene (AQDA) was introduced and it displays an intriguing reversible thermochromism with a green-to-orange red color transition at a wider temperature range from 20-100 oC in solution by the strong hydrogen bonding and aromatic interactions of the headgroups.

制备具有部分可逆热变色特性的氨基喹啉功能化聚二乙烯基杂化囊泡

开发具有可逆热变色特性的智能材料在传感器、显示器和防伪领域具有重要意义。本文合成了一种以氨基喹啉为头基团的二乙炔单体（AQDA）。与荧光素取代二乙炔（FDA）和 10,12-五碳二炔酸（PCDA）一起，通过自组装和拓扑化学聚合过程获得了杂化 PDA 囊泡。混合 PDA 囊泡（FDA、AQDA 和 PCDA 的摩尔比为 7:2:1）在 20 至 100 ℃ 的较宽温度范围内显示出部分可逆的绿色至橘红色的比色变化，这集中体现了较强的氢键和芳香族相互作用。这项工作可为设计可逆热致变色 PDA 材料提供对其机理和策略的基本认识。
