摘　　要：在1-乙基-(3-二甲基氨基丙基)碳二亚胺盐酸盐(EDCI)和1-羟基苯并三唑(HOBT)的催化作用下,对甲酰胺基苯甲酸与1-(4-氨基苯)-1,2,2-三苯乙烯发生酰胺化缩合反应得到4-甲酰胺基-N-(4-(1,2,2-三苯基乙烯基)苯基)苯甲酰胺。4-甲酰胺基-N-(4-(1,2,2-三苯基乙烯基)苯基)苯甲酰胺再经过异腈化反应得到单体4-异氰基-N-(4-(1,2,2-三苯基乙烯基)苯基)苯甲酰胺(PITPE)。PITPE在二氯二(三苯基膦)镍的催化下,得到聚合物聚-苯异腈四苯乙烯酰胺(Poly-PITPE)。PITPE和Poly-PITPE的结构经过^(1)HNMR、FT-IR表征。Poly-PITPE经过荧光光谱分析,在水和四氢呋喃的体积比为9∶1的混合体系下发光强度最高。Catalyzed by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride(EDCI) and 1-hydroxybenzotriazole(HOBT),4-formamidon-(4-(1,2,2-triphenylvinylphenyl)phenyl)benzamide was obtained via amidation and condensation reactions involving p-formamidobenzoic acid and 1-(4-aminobenzene)-1,2,2-triphenylvinylphenyl.Subsequently,this compound was isonitrileted to yield the monomer 4-isocyanon-(4-(1,2,2-triphenylvinylphenyl)phenyl)benzamide(PITPE).The monomer was catalyzed by nickel dichloride in the presence of triphenylphosphine,resulting in the formation of the polymer poly-phenylisonitrile tetraphenylamide(Poly-PITPE).The structural characteristics of PITPE and Poly-PITPE were elucidated through ^(1)HNMR and FT-IR analyses.The fluorescence spectroscopy analysis showed that Poly-PITPE had the highest luminescence intensity in a mixed system of water and tetrahydrofuran with a volume ratio of 9∶1.
