Multifunctional applications of difluoroboron β-diketonate complexes

Difluoroboron β-diketonate complexes (BF₂bdks) are a versatile class of luminescent materials, notable for their high fluorescence quantum yields, excellent photostability, and tunable emission properties. Driven by advances in molecular design and materials processing, BF₂bdks have demonstrated great potential across diverse application fields. This review summarizes recent progress in their implementation, including organic room-temperature phosphorescent materials, stimuli-responsive materials, optoelectronic devices, and luminescent probes. Representative examples are highlighted to illustrate the key structure-property relationships, notable performance improvements, and emerging design strategies. By providing a concise yet comprehensive overview of the application landscape, this review aims to inspire further exploration of BF₂bdk-based optical materials.
