Paper Abstract

Optical excitation at low temperature of pentacene guest molecules in benzoic acid crystals leads to the appearance of a great variety of defect structures. The reaction mechanism proposed is the transfer of a proton from the matrix to the dye forming a very unstable hydrogenated complex of pentacene which relaxes to ground state pentacene and a proton in a defect position of matrix. These results may serve as model for the study of spectral holeburning and spectral diffusion processes in amorphous solids.
