“…In addition, the quantum-chemical calculations have shown the Bp π -Op π bonding is more than 4 times weaker than both Оp π -С α p π and С α p π -С β p π bonding, thus indicating the absence of the ring current. The results of the detailed investigation of the electronic structure of the dioxaborine core, including the energies and spatial distribution of the molecular orbitals, as well as the X-ray and spectral data of the simplest dioxaborines, are reported elsewhere [46,47,[50][51][52][53].…”

Aim. To summarize and analyze literature data on the polymethine dyes containing the 2,2-difluoro-1,3,2-dioxaborine ring.Results and discussion. Boron difluoride complex of β-diketone (2,2-difluoro-1,3,2-dioxaborine, F2DB) is a unique structural motif endowing organic compounds with prominent physicochemical properties, such as a strong fluorescence and high mo-lar attenuation coefficients. Incorporation of the F2DB core into a polymethine chromophore either as an end-group or as an integral part of the polymethine chain allows obtaining dyes with exceptional characteristics, highly appealing for design of up-to-date functional materials. This review focuses on the synthesis and spectral properties of the F2DB-containing polymethines along with the latest advancement in the synthesis of highly fluorescent polyanionic polymethines. A brief discussion of the effects of the structural modification of the π-conjugated system on the photophysical properties of dyes is included.Conclusions. The literature on the F2DB-containing polymethines demonstrates a high potential of the F2DB core for the development of strongly fluorescent and intensely absorbing dyes.
