Abstract
A new functionalized copillar[5]arene derivative containing one 1,4-bis(hexadecyl)benzene unit and four 1,4-dimethoxybenzene units has been synthesized and revealed to present self-assembly driven by C-H···π and cation···π interactions in CD3CN solution, giving a constructed supramolecular polymer gel accompanied by aggregation-induced enhanced emission (AIEE) of fluorescence. When adding a surfactant bearing hexadecylpyridinium chloride into the gel, the electron-poor compound penetrated into the rich-electron cavity of DCP5-16, forming host-guest complexation and causing fluorescence quenching due to the electron transfer. This approach may open up routes to novel stimuli-responsive supramolecular materials.
