Research output: Chapter in Book/Report/Conference proceedingConference contribution


We develop a theory of the electronic structure and photophysics of interacting chains of π-conjugated polymers to understand the differences between solutions and films. While photoexcitation generates only the exciton in solutions, the optical exciton as well as weakly allowed excimers are generated in films. We explain the nonexponential time decay of photoluminescence in films. We also explain photoinduced absorptions in films, which are primarily from the lowest excimer.
