•N,N-dimethylaminostyryl-β-diketonates of boron difluoride were synthesized.•Two luminescent processes were revealed for the compounds.•The quantum chemistry simulation of absorption spectra was calculated.•These compounds form hydrochloride with a bright luminescence.
Spectral-luminescence properties of several dimethylaminostyryl-β-diketonates of boron difluoride with different α-substituents have been investigated through stationary and time-resolved spectroscopy. Quantum chemistry studies of the structure of excited states of 2,2-difluoro-4-(4′-dimethylaminostyryl)-6-phenyl-1,3,2-dioxaborine have been performed. Two luminescence centers have been revealed for the compound under study: an intensive band in the red–orange region of the spectrum caused by an S1–S0 transition and a short-wave luminescence in the blue region of the spectrum caused by an S2–S0 transition.
