摘　　要：以2,7-二溴-9,9-二苯基芴为起始原料,采用发散合成策略,合成了一种新型三苯胺树枝状分子——2,7-二[N,N-二(4-二苯胺基苯基)胺基]-9,9-二苯基芴(FTPA),其结构经1H NMR,13C NMR,HR-MS和元素分析表征。并对其热稳定性、光谱性质和电化学性质进行了研究。结果表明:FTPA的热分解温度和玻璃化转变温度分别为592℃和154℃;FTPA的吸收峰位于309 nm,349 nm和409 nm,最大发射波长为465 nm;FTPA的第一、第二及第三氧化电势分别为0.37 V,0.49 V和0.83 V。A novel dendrimer based on triphenylamine, N2, N2, N7, N7-tetrakis [ 4-（ diphenylamino ） phenyl]- 9,9-diphenlyl-Fluorene-2,7-diamine（ FTPA）, was synthesized according to divergent strate- gy, using 2,7-dibromo-9,9-diphenyl fluorine as starting material. The structure was characterized by 1H NMR, 13C NMR, HR-MS and elemental analysis. The thermal stability, the spectral property and electrochemical property of TYPA were studied. The results indicated that the decomposition tempera- ture and glass transition temperature were 592 ℃ and 154 ℃, respectively. Three absorption peaks were observed at 309 nm, 349 nm and 409 nm, with a maximum emission wavelength at 465nm. The first, second and third oxidation potential of FTPA were measured at 0.37 V, 0.49 V and 0.83 V, re- spectively.
