Facile preparation and application of luminescent cucurbit[10]uril-based porous supramolecular frameworks

Herein, we report the facile preparation of two solid luminescent materials made from cucurbit[10]uril-based porous supramolecular assemblies , from simple precipitation of cucurbit[10]uril (Q[10]) in HCl solution (A) or HNO3 solution (B). Loading Q[10]-based porous supramolecular assemblies A or B with various fluorophore guests ( FG s), including dyes and fused ring compounds, to yield solid luminescent materials ( FG @ A s and FG @ B s) that exhibited fluorescence enhancement or colour changing fluorescence emission . Moreover, these solid luminescent materials could respond to certain volatile organic compounds, demonstrating promise as solid sensors.
