Abstract

Abstract : We report N, O-boron-chelated dipyrromethene derivatives exhibiting circularly polarized luminescence (CPL) in the red/near-infrared region, with enhanced |glum | values from 10 −4 in solutions to 10 −2 in aggregate states. Abstract : We report N, O-boron-chelated dipyrromethene derivatives exhibiting circularly polarized luminescence (CPL) in the red/near-infrared region, both in solution and the aggregated state. The CPL is originated from the helical chirality through intramolecular substitution of fluorine by an alkenolic substituent. The self-assembly of the fluorophores significantly enhances the | g lum | values from 10 −4 to 10 −2 .
