| 摘 要： | 以9,9'-螺二芴和不同链长的二烷氧基苯为单体, 以FeCl3为催化剂, 采用化学氧化法合成了一系列聚合物发光材料. 溶解度测试表明, 共聚物在二氯甲烷、四氢呋喃(THF)、氯仿等极性溶剂中具有良好的溶解性. 利用核磁共振氢谱(1H NMR)、傅里叶变换红外(FT-IR)光谱、紫外-可见(UV-Vis)光谱和荧光(PL)光谱研究了共聚物的化学结构和发光性能, 结果表明共聚物在二甲基亚砜(DMSO)中均发射蓝色荧光, 最大吸收和荧光发射峰分别为356和413 nm. 以硫酸奎宁溶液作为参比, 测得共聚物的荧光量子效率为0.69至0.77. 通过循环伏安法(CV)测得所合成的三种共聚物的最高占有分子轨道(HOMO)能级均位于-5.85至-5.69 eV之间.

| Abstract: | Spirobifluorene (SPF)-based soluble copolymers containing different chain lengths of alkoxy-benzene units in the main chain were synthesized via a chemical oxidative method using FeCl3 as the catalyst.The copolymers are soluble in common organic solvents such as methylene chloride,tetrahydrofuran (THF),and chloroform.The chemical structure and luminescence properties of the as-prepared copolymers were investigated by Fourier transform infrared (FT-IR) spectroscopy,proton nuclear magnetic resonance spectrosc... |
