Wan, Peter published the artcileAdiabatic photodehydroxylation of 9-phenylxanthen-9-ol. Observation of carbocation fluorescence in neutral aqueous solution, Safety of 9-Phenyl-9H-xanthen-9-ol, the publication is Journal of Organic Chemistry (1985), 50(16), 2881-6, database is CAplus.
The photobehavior of the title compound (I) is examined in aqueous solution and organic solvents. Aqueous I undergoes adiabatic photodehydroxylation (the first example of a new class of adiabatic photochem. reactions). The reaction is not observed in MeCN and 95% aqueous EtOH. The photogenerated carbocation is trapped by MeOH in aqueous MeOH. The photobehavior of I is due to the enhanced basicity (as measured by the ionization constant pKR+ of the mol. in S1 relative to that of the ground state (S0). The enhanced electron-donating effect of the ortho atom of I in the excited singlet state is responsible for this effect.
