difluoroborates were
synthesized, and their photophysical properties were determined. The
effect of the substituent and benzoannulation on their properties
was investigated to make a comparison with recently published results
focused on related quinolines. The photophysical properties of isoquinoline
derivatives differ from those of quinolines, and the most pronounced
differences are found for the fluorescence quantum yields. Both experimental
and theoretical approaches were used to explain the observed photophysical
properties.
