| Abstract: | The nonlinear optical properties of newly synthesized organic compounds have been investigated by use of the analytic response field method at density functional theory level. The numerical results show that this kind of molecules has strong two - photon absorption cross - sections. The two - photon absorption of molecules is related to the molecular plane besides the strength of donor and acceptor for pulling and pnshing, electrons. |
