Benzofluorenone dyes are known to exhibit strong solvatochromic properties and are sensitive to the position of electron donating groups on the phenyl ring of the chromophore. In this study we will estimate the changes in the excited state dipole moments as a function of electron donation ability and as a function of substituent position by carrying out Lippert-Mataga analyses.
