基于Rhodol衍生物的电响应多重手性光学开关体系
An Electrically Responsive Multiple Chiroptical Switching System Based on a Rhodol Derivative
摘要
Abstract
In this study,a chiral aniline structure was introduced into the 3′-amino-6′-hydroxyspiro[2-benzofuran-3,9′-xanthene]-1-one(Rhodol)derivative main molecule,which exhibits pH(acid and base)-responsive color changes.Then,based on the proton-coupled electron transfer mechanism,a novel electrically responsive multiple chiroptical switching system was constructed by integrating the functional Rhodol derivative with electro-acid/base molecules.Controlled by suitable voltages,this system could switch among three circular dichroism absorption states reversibly:in the visible light range,no circular dichroism signal at the initial state,positive circular dichroism signal under a significant positive voltage,and negative circular dichroism signal under a considerable negative voltage.More importantly,all the switching processes were totally reversible.This research opens a new route to achieve the development of electrically responsive multiple chiroptical switching systems,and offers an important insight on the design and application of innovative materials for multiple chiroptical switches.关键词
