摘　　要：以2,2'∶6',2″-三联吡啶为电子受体(Acceptor,A)基元,通过Wittig成烯反应引入N-己基-3-甲酰基咔唑电子给体(Donor,D)基元,合成了一种D-π-A型三联吡啶衍生物,对其进行了质谱、核磁共振波谱、红外光谱及X射线单晶结构分析.光学性质研究结果表明,目标产物具有单、双光子吸收和荧光特性,荧光量子产率(Ф)高达0.46,最大双光子吸收截面(δ)为120 GM.A D-π-A type 2,2′∶6′,2″-terpyridine derivative was synthesized by Wittig reaction using 2,2′∶6′,2″-terpyridine as an acceptor（A） and 3-formyl-N-hexylcarbazole as a donor（D）,its structure was characterized by means of MS,FTIR,1H NMR,13C NMR and single crystal X-ray diffraction.For the D-π-A type terpyridine derivative,its linear absorption,single-and two-photon properties were measured and the results showed that the target compound has good fluorescence with the fluorescence quantum yield（Ф） up to 0.46 and the maximal two-photon absorption cross section（δ） up to 120 GM.
