Abstract：Spectral properties of a series of new heterocyclic molecules were studied in the present work. The spectral experimental results show that the two-photon absorption cross-sections of these new molecules are dependent on their charge transfer dipole moments, which relate to the donor acceptor end groups. At high density pumping, the spectral and temporal properties of the high directional emission of a new molecule with two-photon absorption cross-section of 617.3 GM demonstrate that three-photon induced lasing occurs.
