Abstract Sn←S1 absorption spectra of 9,9′-bianthryl in the visible and near infrared regions have been measured by means of picosecond flash spectroscopy. The Sn←S1 spectra in hexane measured at 500 ps after the exciting pulse were similar to those of anthracene while those in acetone were similar to the superposition of spectra of anthracene anion and cation. The results of the Sn←S1 spectral measurements together with those of the solvent effects upon the fluorescence yield and lifetime indicate an intramolecular electron transfer induced by the interaction with polar solvents in the excited state of 9,9′-bianthryl.
