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

Research output: Contribution to journal › Article › peer-review

Abstract

Purely conformational contributions to dipole transition moments lead to a general new expression for the absorption spectrum of flexible conjugated polymers with persistence length ξ_c 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.
