| 中文摘要: |
| 将扭曲并苯分子单元引入到聚合物中能够有效减弱聚合物固相下聚集,为发展高荧光的有机显示材料提供新的思路,为此,通过经典Suzuki偶联反应,合成了四种新型的含有扭曲并苯分子的线性聚合物(P1-P4)。在四氢呋喃溶剂和固体薄膜下,聚合物在302-417 nm处有两个宽的吸收峰,峰形状类似, 发出蓝色荧光,且薄膜的发射波长红移。四种聚合物重量损失为5%时的温度都高于350℃,表明都具有良好的热稳定性。通过循环伏安法测定其电化学行为。 |
| 英文摘要: |
| The introduction of twistacene unit into polymers can decrease the fluorescence quenching in the solid state, which provides more room to approach the electroluminescent materials. Four novel linear twistacene-functionalized polymers P1-P4 are synthesized through classical Suzuki coupling reaction. In THF solution and thin film, all of them show similar absorption profiles and have two broad absorption peak between 302nm and 417nm. In thin film, the red shift of wavelength of fluorescence emit was found and all of them can emit strong blue fluorescence. TGA analysis suggested that P1-P4 were stable up to 350℃. In addition, the electrochemical behavior was further tested using CV method. |
