摘要：

Throwing light on encapsulation: The fluorescent probe molecule 4-[3-(9-anthryl)propyl]-N,N-dimethylaniline (C gray, N blue) crystallizes either exo or endo to the cavity of pyrogallol[4]arene hexamers (O red) and displays markedly different fluorescence emission behavior as a result. In the exo array, the guest alters the packing of the hexamer by forming channels through the extended structure in the solid state (see picture).
