摘　　要：Conformational regulation among two or more distant sites is not only one of the main pathways to accomplish multiple tasks in complex biological systems but also represents a powerful strategy to obtain stimuli-responsive supramolecular nanoconstructs with tailored physicochemical performance.We herein report the fabrication of a photochromic supramolecular assembly,which can be synergistically activated by the conformational regulation with bis(4,8-disulfonato-1,5-naphtho)-32-crown-8 and then reversibly switched by the through-space communication between restricted stilbazolium salt and photochromic dithienylethene.This work demonstrates that the synergistic conformational modulation via intra-and intermolecular interactions can be developed as a generalizable approach to construct more advanced biomimetic nanomaterials.
