MIGRATION OF ENERGY OF ELECTRON-EXCITED M OLECULES INTO A POLYMERIC GLASSY SOLVENT AND THE POSSIBLE ROLE OF LOCAL HEATING IN CHEMICAL PROCESSES IN CONDENSED-PHASE

Fast photoinduced processes observed in the cis-trans-rearrangement of azo compounds in polymeric glassy templates were studied. The rate of the processes in polymers can exceed the rate of similar processes in liquid low-molecular weight solvents. It was found by the method of l inear electrochromism that the nature of fast processes is due to the storage of a part of light energy in the nearest surroundings of molec ules. It is assumed that local heating plays a role in photochemical r eactions in the condensed phase, including photobiochemical processes.
