We have theoretically studied on the geometrical structure, electronic structure, one-photon absorption(OPA) and two-photon absorption(TPA) properties of perylene tetracarboxylic derivatives(PTCDS) by using DFT and ZINDO methods. The investigation indicated that TPA cross-section of PTCDS are mainly determined by their main body (perylene), to decrease the △EH-Lgap (energy gap between HOMO and LUMO) , to increase the energy of HOMO, to increase the strength of donor group on lateral side, to extend the conjugated length and to increase the rigidity of molecular are all efficient way to increase TPA cross-section of PTCDS. Finally, we have designed the two new molecules with bigger TPA cross-section than molecules C refered in the references[22].

Key words: electronic structure, one- and two-photon absorption, two-photon absorption cross-section
