Acid/base-controllable fluorescent molecular switches based on cryptands and basic N-heteroaromatics

Author affiliations

Abstract

Two kinds of fluorescent BMP32C10-based cryptands 1 and 2 have been developed. Cryptand 1 contains a binaphthol group, while cryptand 2 bears a coumarin group in their third arms. Based on this design, novel self-assemblies constructed from cryptand 1 or 2 and basic N-heteroaromatic guests 3–6 were successfully obtained. Moreover, the threading/dethreading processes of the host–guest complexes could be well switched by the alternate addition of acid/base, and accompanied by concurrent changes in fluorescence.
