Abstract : Although the ground-state charge transfer complexes of pi-conjugated polymers have been widely investigated in the past two decades, the corresponding excited-state complexes were only recently discovered. The results of our extensive studies of intermolecular excimers and exciplexes of many conjugated polymers will be presented in the talk. The observation of excimer and excimer emission of many conjugated polymers provides a new model of the photophysics of the materials. It will be shown that the modified Birks' mechanism of intermolecular excimers can explain all the essential features of the luminescence of conjugated polymers. The luminescence and charge photogeneration in exciplexes of conjugated polymers with donor triarylamines will also be presented. jg
