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.
