摘　　要：以2,5-二溴对苯二甲酸甲酯为起始原料,设计并合成了3个新型的对三联苯衍生物(5,7,8),其结构经1H NMR,13C NMR,EI-MS,元素分析和X-射线单晶衍射表征。用UV-Vis和FL考察了5,7和8的光学性能。结果表明:5,7和8的λmax分别位于229 nm,244 nm和244 nm;在340 nm激发波长激发下,5,7和8的λem均位于430 nm。Three novel p-terphenyl derivatives（ 5,7,8） were designed and synthesized from 2,5-dibromoterephthalate. The structures were characterized by1 H NMR,13 C NMR,EI-MS,elemental analysis and X-ray diffraction. The optical properties of 5,7 and 8 were investigated by UV-Vis and FL. The results showed that λmaxof 5,7 and 8 were 229 nm,244 nm and 244 nm,respectively. λem of 5,7 and 8 were 430 nm（ λex= 340 nm） 。
