• -fitting synthetic capsules. However, trans-stilbene has been recently studied in the context of antibody interiors, where binding results in strong blue fluorescence. The present research was undertaken to understand the spatial factors that influence stilbene fluorescence. trans-Stilbene was encapsulated

• : molecular twisting; quenching; reversible encapsulation; self-assembly; stilbene fluorescence; Introduction The fluorescence of trans-stilbene has been extensively researched [1], and weak fluorescence occurs in aqueous solutions or typical organic solvents. In a highly structured environment such as an

• at the ends and square prisms of the heterocyclic walls near the middle. The quenching of stilbene fluorescence may be an effect of the fixed aromatics of the resorcinarene or the heterocyclic walls, but we surmised that there was a subtler cause. As seen in the skeletal model 1.1 of the space within
