Circularly polarized luminescence from decamethylcucurbit[5]uril-triggered chiral supramolecular hydrogels†

Abstract

Fluorescence resonance energy transfer (FRET) is observed in the supramolecular hydrogels assembled by decamethylcucurbit[5]uril and (R/S)-BINAM upon the addition of sulforhodamine B, tuning the emission from blue-green to red. High circularly polarized luminescence asymmetry factor and near-white light emission are achieved, offering a new strategy for white CPL material design.
