摘　　要：A novel two-photon absorption material with spiorsilabifluorene as π-conjugated bridge,and electron-donating triphenylamine as the terminal groups was synthesized,which consists of a typical D-π-D structure.The nonlinear optical properties,glass transition temperature and two-photon fluorescence imaging have been characterized.Experimental results show that the optimal combination of nonlinearity、transparency and thermal stability of two-photon absorption material can be achieved by introducing spiorsilabifluorene as π-conjugated bridge,and indicate that the new π-conjugated bridge benefits blue emission.This is an entirely new concept,which may open a new pathway to the design and synthesis of two-photon absorption materials,and has attractive prospect.A novel two-photon absorption material with spiorsilabifluorene as ,π-conjugated bridge, and electron-donating triphenylamine as the terminal groups was synthesized, which consists of a typical D-π-D structure.
