Abstract

The various photochemical processes (luminescence, non-radiative transition to the ground state, electron and energy transfer, isomerization, addition, hydrogen abstraction, and fragmentation), the most important technical applications of photochemistry are reviewed. The main applications of luminescence phenomena are optical bleaching of textiles and paper. Rapid radiationless transitions to the ground state often brought about by means of quenchers or of thermos reversible light reactions, are necessary for light protection of plastics and human skin. Electron and energy transfer processes have found a wide range of applications in photography, preparative photochemistry, and light sources, respectively. Photofragmentations are used in reprography and in the photochemical synthesis of detergents, insecticides and monomers for polyamides. Keywords: photochemical processes, luminescence, non-radiative transition to the ground state, electron and energy transfer, isomerization, addition, hydrogen abstraction, and fragmentation
