Design of Dimeric Dinuclear Boron Complexes with Flexible Linkers: Aggregation-induced White-light Emission via Molecular Engineering

The aggregation state of two new covalently bonded dinuclear boron-based dye complexes was controlled to fabricate white-light-emitting materials. The materials exhibit blue and orange emission, with a photoluminescence quantum yield of 16% for one of the complexes in the solid state. This study highlights the importance of molecular engineering through the control of dye aggregation as a fundamental technology for creating novel functional materials with interesting optical properties.
