Photochemical properties of Yt base in aqueous solution.

Abstract

Photoreactivity of Yt base [I] has been studied in aqueous solution [pH approximately 6] saturated with oxygen. Two photoproducts (II,III], resulting from irradiation at lambda = 253.7 nm and lambda greater than or equal to 290 nm, were isolated and their structures determined. The quantum yield for Yt base disappearance [zeta dis] is 0.002 [lambda = 313 nm]. It was shown that dye-sensitized photooxidation of Yt base in aqueous solution occurs according to a Type I mechanism, as well as with participation of singlet state oxygen. Quantum yields, fluorescence decay times and phosphorescence of Yt base have been also determined.
