The photophysical properties of Bisoprolol at pH = 7.4 in different solvents and under different conditions have been studied. It was found that Bisoprolol exhibits a characteristic absorption band at 223 nm and 275 nm and emission band at 295 nm. The nature of solvent was found to affect significantly the position of these bands especially the non-polar solvent. Different pH aqueous media was used to interaction with Bisoprolol to measuring pKa and pKa*. In this research the role of electron transfer and energy transfer was studied. Semiconductors are the best materials that used as electron donor or electron acceptor, acid and base also used. Viologens are used to interaction with Bisoprolol by energy transfer. The lifetime of Bisoprolol was also studied under different conditions and with different materials
