摘要

The synthesis of a serial new triphenylamine-multibranching chromophores with porphyrins "core" were reported and UV-vis absorption, one/two-photon fluorescence and two-photon absorption (TPA) cross-section were investigated. The triphenylamine-branching effect on their properties, including the different branches numbers and different generational multibranches were investigated in detail. The results show the different branches numbers and the different generational multibranches had a remarkable effect on the absorption and one/two-photon fluorescence properties of these chromophores. The two-photon absorption cross-section value (σ_s) of the higher generational multibranched triphenytamine chromophore TPP-(G2X)_3 is 1058.25 GM, which is three times bigger than the others. Comparatively, the higher generational multibranched triphenylamine effect shows more significant contribution to two-photon absorption enhancement and obviously improves two-photon absorption cross-section behavior. This is greatly valuable for designing and synthesizing novel TPA materials.
