Solvent effects on the three-photon absorption of a symmetric charge-transfer molecule

Density functional theory (DFT) cubic response theory and the polarizable continuum model are used for studying the solvent-induced three-photon absorption cross section of a highly conjugated fluorene derivative. It is shown that the simplified model performs poorly for the three-photon absorption properties of the symmetric charge-transfer molecule and the dielectric medium has increased the three-photon absorption cross section.
