摘要：Novel styryl derivatives with triphenylamine as donor and 1,3,5-triazine as acceptor were synthesized and their one- and two-photon properties were investigated. These molecules show large two-photon absorption (TPA) cross sections and strong Z7 two-photon fluorescence. TPA cross section is as large as 1.64 x 10(-20) cm(4) /GW for the tri-branched molecule.
