Abstract

Hydrogen-bonded solute-(solvent)_n, n = 0, 1, 2 complexes have been produced and spectro-scopically characterized in cryogenic rare gas matrices. The solutes studied can undergo excited state proton transfer and include 2-hydroxy-4,5-benzotropone, 3-hydroxyflavone and 3-hydroxychromone. The solvents include water and alcohols. The fluorescence excitation and dispersed emission spectra of each complex stoichiometry have been determined by dilution and matrix annealing studies. Excited state proton transfer in each type of complex has been studied by picosecond emission spectroscopy. The proton transfer dynamics were found to vary dramatically with the degree of solvation.
