一种推拉型A-D-A蒽衍生物9，10-二{4-{2-N，N-二{4-{4-[5-（4-叔丁基苯基）-1，3，4-噁二唑-2]苯乙烯基}苯基}胺基}苯乙烯基}蒽（An-BPOAS）由四碘代芳香化合物9，10-二{4-[N，N-二（4-碘苯基）氨基]苯乙烯基}蒽（An-BIPAS）与芳基乙烯通过钯催化Heck偶联反应制备. 用飞秒Ti：sapphire激光测定了9，10-二芳基蒽树形分子An-BPOAS的多光子吸收系数和多光子诱导荧光光谱. 在1300 nm飞秒激光激发下，An-BIPAS和An-BPOAS的三光子荧光峰分别位于553和539 nm. 1300 nm飞秒激光激发下采用非线性透过率法测得An-BIPAS和An-BPOAS的三光子吸收系数分别为0.3×10-5和1.5×10-5 cm3/GW2. 测定了树形分子An-BPOAS的线性吸收和荧光性质. 实验测定了不同pH值化合物An-BPOAS在DMF/H2O混合溶液中的荧光光谱. 化合物An-BPOAS具有良好的荧光性能，可作为性能良好的双光子及三光子吸收及荧光材料.

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.
