Excited-state proton transfer in gas-expanded liquids: the roles of pressure and composition in supercritical CO2/methanol mixtures.
Excited-state proton transfer from 5,8-dicyano-2-naphthol to methanol takes place in CO2/methanol mixtures, in the pressure and temperature ranges of supercritical CO2. The efficiency of the proton-transfer step decreases with the pressure. This is assigned to the perturbation of the methanol clusters solvating the naphthol.
