Abstract

A newly designed anthracene derivative having gluconamides at its peripheral branches formed a photo-responsive hydrogel. SEM observation of the xerogel showed a network structure consisting of fibrils. Upon photoirradiation (lambda >300 nm) of the hydrogel, regioselective photodimerization of the anthracene moiety occurred to give head-to-tail photodimers and the physical state changed from the gel to the sol.

摘要

一种新设计的在其外围分支带有葡糖酰胺的蒽衍生物形成了一种光响应水凝胶。对干凝胶的扫描电子显微镜观察显示出由原纤维组成的网络结构。对该水凝胶进行光照射（波长>300nm）时，蒽部分发生区域选择性光二聚化，生成头对头光二聚体，并且物理状态从凝胶变为溶胶。
