Conjugation-Length Dependence of Spin-Dependent Exciton Formation Rates in Pi-Conjugated Oligomers and Polymers

M. Wohlgenannt, X. M. Jiang, Z. V. Vardeny +1

We have measured the ratio, r = ${\sigma }_S/{\sigma }_T$ of the formation cross section, $\sigma$ of singlet (${\sigma }_S$) and triplet (${\sigma }_T$) excitons from oppositely charged polarons in a large variety of…
