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的聚集,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4种新型的含有扭曲并苯分子的线性聚合物(P1~P4)。在四氢呋喃溶剂中或固体薄膜下,聚合物在302~417 nm处有2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。4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。通过循环伏安法研究了聚合物的电化学性质。
The introduction of distorted benzene molecules into the polymer can effectively weaken the aggregation of the polymer solid phase, providing a new idea for the development of high fluorescence organic display materials. To this end, four novel linear polymers containing distorted benzene molecules (P1 ~ P4) were synthesized by classical Suzuki coupling reaction. In tetrahydrofuran solvent or solid film, the polymer has two broad absorption peaks at 302 ~ 417 nm, the shape of the peak is similar to blue fluorescence, and the emission wavelength of the film is red-shifted. Four polymers at 5% weight loss all had temperatures above 350 ° C, indicating good thermal stability. The electrochemical properties of the polymer were investigated by cyclic voltammetry.
