Abstract

The photon absorption spectra for donor-π-donor (D-π-D), donor-π-acceptor-π-donor (D-A-D) and acceptor-π-donor-π-acceptor (A-D-A) molecules, which have been measured using two-photon induced fluorescence method, is discussed. The lowest-energy two-photon absorption for these system can be well described by a Sum-Over-States expression in which only three electronic levels play a significant role: the ground state, the lowest-dipole allowed state, and the two-photon state. An additional increase in transition dipole moment M_ee is observed in the D-A-D and A-D-A systems.
