Here, we describe a “smart” polymeric material, which is able to readily detect and discriminate amine vapors. The dynamic imine-based network can be conveniently prepared by mixing a commercially available, amino-functionalized polysiloxane with small amounts of a diarylethene dialdehyde. The photoswitchable crosslinker allows for reversible imprinting of custom-designed patterns on the polymer surface with (sun)light and thus enables noninvasive information storage in the material, which before, during, and after amine exposure can readily be decoded with commonly used smartphone apps. This feature along with the self-healing nature of the dynamic polymer, an easy recycling and manufacturing procedure, and the overall low cost and toxicity render this material advantageous to develop low-cost and practical amine sensing devices for the broad public. © 2019 The Authors.

基于亚胺的动态聚合物网络作为光可编程胺传感装置

在这里，我们描述了一种“智能”聚合物材料，它能够轻松检测和区分胺蒸气。动态亚胺基网络可以通过将市售的氨基官能化聚硅氧烷与少量二芳基乙烯二醛混合来方便地制备。光可切换交联剂允许使用（太阳）光在聚合物表面上可逆地印上定制设计的图案，从而能够在材料中进行非侵入性信息存储，在胺暴露之前、期间和之后，可以使用常用的智能手机应用程序轻松解码。此功能以及动态聚合物的自愈特性、易于回收和制造过程，并且整体的低成本和毒性使这种材料有利于为广大公众开发低成本和实用的胺传感装置。© 2019 作者。高分子科学杂志 A 部分： Wiley Periodicals, Inc.
