A Push Pull ADA Anthracene Derivative 9,10-Bis {4- {2-N, N-Bis {4- {4- [5- (4-tert-Butylphenyl) 2-styryl} phenyl} amino} styryl} anthracene (An-BPOAS) was synthesized from tetraiodo aromatic compound 9,10-bis {4- [N, Amino) styryl} anthracene (An-BIPAS) and aryl ethylene were prepared by palladium-catalyzed Heck coupling reaction.The 9,10-diarylanthracene dendrimer An-BPOAS was determined by femtosecond Ti: sapphire laser Photon absorption coefficient and multiphoton-induced fluorescence spectra.Under the 1300 nm femtosecond laser excitation, the three-photon fluorescence peaks of An-BIPAS and An-BPOAS are located at 553 and 539 nm, respectively, The three-photon absorption coefficients of An-BIPAS and An-BPOAS measured by transmittance method were 0.3 × 10-5 and 1.5 × 10-5 cm3 / GW2, respectively. The linear absorption and fluorescence properties of the dendrimer An-BPOAS were measured. The fluorescence spectra of different pH compounds An-BPOAS in DMF / H2O mixed solution were determined experimentally.The compound An-BPOAS has good fluorescence properties and can be used as a good two-photon and three-photon absorption and fluorescence material.
