Multicolor Luminescent Supramolecular Bidirectional Shuttles Driven by Light.

ABSTRACT: Possessing special photophysical behavior, supramolecular space-confined assembly is widely applied in bioimaging, information anti-counterfeiting, and luminescent materials. Herein, two different multicolor luminescent supramolecular bidirectional shuttles driven by light are reported, which are constructed by spiropyran-modified p-styrene derivatives (BPSP), cucurbit[7]uril (CB[7]) and cucurbit[8]uril (CB[8]). CB[7] encapsulated BPSP not only effectively enhance the fluorescence intensity both in the ring-closed and ring-open states accompanied with multicolor luminescence from blue to red, but also produce ortho-hexagonal nanosheets. Different from CB[7], the binding of CB[8] to BPSP formed a nanospherical topological morphology. It induce the red-shift of fluorescence from blue to yell
