| 摘 要： | 通过Wittig法合成了一种新型三苯胺-噁二唑超支化共轭聚合物HPTPA-OXD, 通过IR, 1H NMR, 凝胶渗透色谱(GPC)等对其结构进行了表征. 测定了HPTPA-OXD在不同溶剂中的紫外吸收光谱、荧光光谱、荧光寿命及量子产率. HPTPA-OXD在甲苯, CHCl3, THF, CH2Cl2, DMF溶液中的荧光发射峰分别为473, 497, 507, 522和547 nm, 在CH2Cl2, 甲苯和THF中量子产率分别为0.33, 0.31和0.18, 在THF, CH2Cl2, DMF中的荧光寿命分别为1.24, 1.39和1.14 ns. 电化学性能用循环伏安法测定, 超支化荧光聚合物HPTPA-OXD的HOMO和LUMO能级分别为－4.91和－2.44 eV. HPTPA-OXD的分解温度为440 ℃, 热稳定性良好.

| Abstract: | A novel hyperbranched fluorecence polymer(HPTPA-OXD) containing triphenyamine and 1,3,4-oxadiazole was synthesized by the Wittig reaction.The structure of the polymer was characterized by IR,1H NMR and GPC(gel permeation chromatography).The photophysical properties including UV-vis spectra,fluorescence spectra,and fluorescence lifetime were investigated.The maximum emission wave-lengths were 473,497,507,522 and 547 nm in toluene,CHCl3,THF,CH2Cl2 and DMF respectively,and the fluorecence lifetime were 1.24,1.... |
