摘　　要：以二苯硫醚和咔唑为原料,合成了一种以碳碳三键作为桥接基团的新共轭炔基咔唑分子4,4'-二((N-乙基咔唑-3)-乙炔基)苯基硫醚(CZ-S-CZ),其结构经IR、~1HNMR和^(13)CNMR进行表征。通过紫外-可见吸收光谱研究表明,该物质在300~400 nm有较强的吸收。单光子荧光发射光谱研究表明,该化合物的单光子荧光最大发射波长是382 nm,荧光量子产率达到0.4。双光子激发荧光光谱研究表明,CZ-S-CZ在750~780 nm间具有双光子吸收性能,其双光子吸收截面最大可以达267.2 GM。A novel dye 4,4＇-bis（（ N-ethylcarbazole-3）-ethynyl） phenyl sulfide（ CZ-S-CZ） with a carbon-carbon triple bond as bridging group was synthesized from carbazole and diphenyl sulfide. The structure was confirmed by IR,1HNMR and13 CNMR. The UV-vis absorbance spectrum showed that the substance had a strong absorption from 300 ~ 400 nm; single-photon fluorescence emission spectrum showed that its single-photon fluorescence emission maxima was 382 nm and its fluorescence quantum yield was 0. 4. Two-photon fluorescence revealed that the compound has two-photon absorptions between 750 ~ 780 nm and the maximum of absorption cross section can be up 267. 2 GM.
