A acceptor-donor-acceptor push-pull anthracene, 9,10-bis{4-{2-N,N-bis-{4-{4-[5-(4-tert-butylphenyl)-1,3,4-oxadiazol-2-yl]-styryl}phenyl}amino}styryl}anthracene (An-BPOAS) was synthesized by Heck reaction of 9,10-bis{4-[N,N-(4-iodophenyl)amino]styryl}anthracene (An-BIPAS) with aryl ethene. The multiphoton absorption and multiphoton induced fluorescence properties of An-BPOAS were measured using a femtosecond Ti:sapphire laser. When pumped with 1300 nm femtosecond laser irradiation, chromophores An-BPOAS and An-BIPAS show fluorescence at 539 and 553 nm, three-photon absorption cross-sections determined by nonlinear transmission method are 1.5×10^-5 cm³/GW² for An-BPOAS and 0.3×10^-5 cm³/GW² for An-BIPAS. The linear absorption and fluorescence properties of An-BPOAS were measured. The fluorescent behaviour of An-BPOAS in different pH was studied.

Key words: 9,10-diaryl anthracene derivatives, Heck reaction, fluorescence properties, multiphoton absorption, multiphoton induced fluorescence
