abstract Difluomborates complexes based on 2'-hydroxyphenones were synthetized and their optoelectronic properties studied in both solution and solid state. These new dyes exhibit fluorescence emission in the visible region at similar wavelengths, intriguingly with higher quantum yields in the solid state than in solution. The enhanced emission in the solid state is rationalized on the basis of the crystal structure of the dyes.
