N2 - Nanosecond laser flash photolysis and time-resolved fluorescence were used to study photochemistry of 4,4-Bis(4-hydroxyphenyl)valeric acid (diphenolic acid, DPA) and complex of DPA with β-cyclodextrin (DPA-βCD) in aqueous solutions. For both systems the primary photochemical process was found to be photoionization with the formation of a hydrated electron-phenoxyl radical pair. Inclusion of DPA in cyclodextrin cavity leads to the great increase of photoionization and fluorescence quantum yield (from 0.01 to 0.14) as well as fluorescence lifetime (from 0.17 to 2.9 ns) due to decreasing of the quenching rate of the singlet excited state of complexed DPA by solvent molecules.
