Dynamics of Long-Lived Polarons in Poly({ital para}-phenylene)-Type Ladder Polymers
Abstract
The {ital X}-band spin-1/2 photoluminescence-detected magnetic resonance of poly({ital para}-phenylene)-type ladder polymer films and solutions are described. The photoluminescence-enhancing resonances are assigned to enhanced nonradiative recombination of long-lived polaron pairs, which are singlet exciton quenching centers. Their behavior is consistent with two distinct polaron lifetimes or a very broad distribution of lifetimes; in solutions they are {approx_equal}10 longer than in films. Distinct lifetimes are discussed in relation to longer-lived intrachain interconjugation segment and shorter-lived interchain pairs. {copyright} {ital 1996 The American Physical Society.}
