Absorption spectrum of flexible conjugated polymers: the weak-disorder limit

Z. G. Soos, K. S. Schweizer

Research output: Contribution to journalArticlepeer-review


Purely conformational contributions to dipole transition moments lead to a general new expression for the absorption spectrum of flexible conjugated polymers with persistence length ξc and alternation δ. Blue-shifts are found at rod-to-coil transitions without invoking rotational defects that break the conjugation. Conformational coupling in the weak-disorder limit increases the effective alternation.
