Abstract
A complex picture of phenylene-based polymers is developed which unifies fe atures of band and molecular exciton models. It incorporates major experime ntal finding in direct and photoinduced optical absorption, stimulated phot oemission and photoconductivity. We give new assignments for the most dispu ted features and identify new ones as edge states. We confirm a low binding energy for the principle emitting exciton and show that it dominates also in the fundamental absorption. Contradictions in the current modeling state -of-art are displayed and discussed.
