Multi-color luminescent crystals derived from dynamic diastereomers of a perylene-substituted binaphthol derivative

Abstract

Herein, we demonstrate a novel strategy for obtaining multi-color luminescent crystals. A perylene-substituted (S)-binaphthol derivative was designed, exhibiting dynamic conversion of diastereomers in solution. Crystallization of the dynamic mixture yielded three crystals with different emission colors, each having a different composition of diastereomers and solvent molecules.
