Abstract

Abstract:

Chiroptical molecular switches have been intensively investigated in recent years due to their broad applications in the fields of optical storage， optical communication， three-dimensional imaging， etc. However， some drawbacks， such as few materials， poor optical tunability and poor stability of current chiroptical molecular switches， hinder their applications to construct a chiroptical switching device with high optical tunability and ideal stability. Thus， how to develop a chiroptical switching system with promising performances is still a serious challenge for the researchers. Herein， based on the reversible ‘electroacid/electrobase’ theory， we designed and synthesized a novel acid-responsive chiroptical molecular switch by introducing a chiral binaphthyl functional group into the acid-sensitive rhodamine structure. A novel chiroptical switching system has been successfully developed by the acid-responsive chiroptical molecular switches combining with electroacid materials， as its chiroptical property can be switched by the electric field reversibly. The results show that the color， fluorescence and circular dichroic（CD） signals of this new material could be reversibly regulated under the control of a suitable electric field. In conclusion， this method provides a brand new idea of constructing new chiroptical molecular switching systems， and it will be beneficial for expending the properties and applications of chiroptical molecular switching materials in the future.
