Description
Summary:The photophysical properties of functional distyryl derivatives of dipyrrometheneboron difluoride (BODIPY) in various solvents have been studied. It was shown that in all solvents, the studied compounds have similar absorption and fluorescence spectra, which are characteristic of the distyryl derivatives of BODIPY. Small bathochromic shifts of the spectra with increasing solvent polarity, as well as insignificant changes in the rate constants of radiative and nonradiative processes, provide evidence that the S 1 states are of the (π,π*) type. These dyes can be used to visualize processes in living systems.
