Light‐Harvesting Hybrid Hydrogels: Energy‐Transfer‐Induced Amplified Fluorescence in Noncovalently Assembled Chromophore–Organoclay Composites

The noncovalent self-assembly of chromophores in an organoclay template results in the formation of fluorescent hybrid hydrogels and films. These clay–dye hybrids act as novel supramolecular scaffolds for light-harvesting as the aminoclay (AC) templates the spatial organization of donor and acceptor molecules to promote Förster resonant energy transfer (see picture; CS=coronene salt, PS=perylene salt).
