The impact of the π-conjugation length on the three-photon absorption cross-section of fluorene derivatives

Ion Cohanoschi, Kevin D. Belfield, Carlos Toro, Florencio Eloy Hernandez

Abstract

We report the effect of pi-conjugation length on three-photon absorption cross-section of fluorene derivatives with different structural motifs. We demonstrate that three-photon absorption is enhanced by extending the conjugated bridge of those systems.
