Abstract
Luminescence in organic conjugated polymers is considered in this arti cle, which tries to clarify some of the issues related to the nature o f the emitting species. A comparison of recent experimental and theore tical data on the exciton binding energy in luminescent poly(arylenevi nylene)s, polyarylenes, and their derivatives (e.g., see Figure) leads to the conclusion that they sustain rather weakly bound polaron-exito ns.
