采用Suzuki偶合法将苯并噻二唑结构单元引入聚芴主链,同时在芴的C-9位上引入烯丙基,合成了可交联发绿光的苯并噻二唑与芴共聚物。通过对共聚物溶液的紫外光谱和荧光光谱研究发现,引入可交联基团烯丙基以后,聚合物的光学性能并未发生明显变化。可交联的共聚物在加入光引发剂后,在紫外光作用下可以进行光交联,并且在照射9 min左右聚合物完全交联。通过对交联聚合物荧光光谱的研究发现,聚合物薄膜在交联前后的荧光光谱基本不变,表明交联对聚合物的发光性能并无影响。交联共聚物薄膜在紫外线的照射下发出明显的绿色荧光。
Crosslinkable green light-emitting benzothiadiazole-fluorene copolymers with allyl groups were synthesized through Suzuki coupling,and the products were successfully crosslinked by UV irradiation.The copolymers with molecular weight over 30,000 can be readily dissolved in common organic solvents,such as chloroform,dichloroethane,tetrahydrofuran.UV and photo luminance spectra of the copolymer solutions show that the allyl groups have no effects on the light emitting properties of the copolymers.After irradiation for about 9 minutes,the film of the copolymer can be crosslinked and the photo luminance spectrum of the crosslinked film show the same as that of the uncrosslinked one.
