中文摘要：

有一个核心和不同捐赠电子的能力组织的 triphenylamine 的四新塑造星的结合的 oligomers (TPA-CZ3， TPA-TPA3， TPA-PTZ3 和 TPA-BT3 ) ， carbazole， triphenylamine， phenothiazine 和 bithiophene，外部单位经由 Heck 反应被设计了并且综合。这些 oligomers 表演在普通器官的溶剂的好溶解度。他们的 photophysical ，电气化学的、电子结构和费用转移在这些塑造星的结合的 oligomers 和 N 之间的性质，N二度( 1-ethylpropyl ) -3,4:9,10-perylene 二度( tetracarboxyl diimide )( EP-PDI )被紫外力的吸收系列调查了，光致发光( PL )系列，周期的 voltammetry ( CV )测量，理论计算并且荧光熄灭。TPA-CZ3， TPA-TPA3 和 TPA-PTZ3 的吸收和荧光是红的结果表演与从 carbazole 增加到 triphenylamine 和 phenothiazine 的外部单位的捐赠电子的能力变了。另外，尽管 bithiophene 组比 carbazole， triphenylamine 和 phenothiazine 有一个更弱的捐赠电子的能力，因为 TPA-BT3 比 TPA-CZ3， TPA-TPA3 和 TPA-PTZ3 有更长的变化形式长度， TPA-BT3 的吸收和荧光 TPA-CZ3， TPA-TPA3 和 TPA-PTZ3 比那些有红移动。triphenylamine 核心和外部单位罐头组成大结合的结构。熄灭性质的荧光显示有效费用转移能发生在塑造星的 oligomers 和 EP-PDI 之间。

英文摘要：

Four new star-shaped π-conjugated oligomers （TPA-CZ3, TPA-TPA3, TPA-PTZ3 and TPA-BT3） with triphenylamine as a core and different electron-donating ability groups, carbazole, triphenylamine, phenothiazine and bithiophene, as peripheral units have been designed and synthesized via the Heck reaction. These oligomers show good solubility in common organic solvents. Their photophysical, electrochemical, electronic structure and charge transfer properties between these star-shaped n-conjugated oligomers and N,N＇-bis（1-ethylpropyl）-3,4：9,10- perylene bis（tetracarboxyl diimide） （EP-PDI） have been investigated by UV-vis absorption spectra, photolumines- cence （PL） spectra, cyclic voltammetry （CV） measurement, theoretical calculations and fluorescence quenching. The results show that the absorptions and fluorescences of TPA-CZ3, TPA-TPA3 and TPA-PTZ3 are red shifted with the electron-donating ability of the peripheral unit increasing from carbazole to triphenylamine and phenothi- azine. In addition, although the bithiophene group has a weaker electron-donating ability than carbazole, triphenylamine and phenothiazine, the absorption and fluorescence of TPA-BT3 have a red shift than those of TPA-CZ3, TPA-TPA3 and TPA-PTZ3 because TPA-BT3 has a longer conjugation length than TPA-CZ3, TPA-TPA3 and TPA-PTZ3. The triphenylamine core and the peripheral units can constitute a large conjugated structure. The fluorescence quenching properties indicate that efficient charge transfer can happen between the star-shaped oligomers and EP-PDI.
