| 摘 要： | 采用Suzuki反应合成了一系列9,9-二辛基芴、芴酮(FO)、2,7-二-(2-噻吩)-9-芴酮(DTFO)、4,7-二-(2-噻吩)-2,1,3-苯并噻二唑(DBT)的二元和三元共聚物。结果表明,通过测试聚合物的光致发光光谱(λ=365 nm),发现薄膜状态下相同配比的共聚物比稀的氯仿溶液中的能量传递更加有效。在二元共聚物中,聚芴向DBT的能量传递比FO和DTFO有效;三元共聚物中,相同配比下芴酮的发射虽然完全淬灭,但是芴酮的引入使得宽窄带隙基团间的能量传递更加有效。

| Abstract: | A series of bipolymers and terpolymers of 9,9-dioctylfluorene,fluorenone(FO),2,7-bis-(2-thienyl)-9-fluorenone(DTFO),4,7-bis(2-thienyl)-2,1,3-benzothiadiazole(DBT) were synthesized by Suzuki.The results show that energy transfer of copolymer in film was more effective than in dilute chloroform solution by testing photoluminescence spectra(λ =365 nm).In bipolymers,the energy transfer from polyfluorene to the DBT was more effective than to FO and DTFO.In terpolymers,the emission of FO was quenched at the same ratio,but the introduction of FO was favorable to energy transfer from wide-band-gap to narrow-band-gap. |
