摘要
以5 甲基 2 氯甲基苯并唑和对二苯甲醛为主要原料,通过两次Wit tig Horner反应,合成了未见文献报道的主链含有苯并唑环的PPV型齐聚物.目的在于在PPV聚合物主链中嵌入电子传输型结构单元,提高聚对苯撑乙烯共轭链的电子传输能力,改变PPV的发光特性.分析数据表明,该齐聚物的 Mw为2500,并且分子结构中的乙烯基CC双键均为反式结构特征.UV Vis吸收光谱特征峰λmax等于497nm.
A new PPV oligomer containing electronrich benzoxazole,which can enhance the electrontransporting in PPV main chain,had been synthesized from 2chloromethylbenzoxazole and pphthalaldehyde by WittigHorner reaction.The analytic data indicated that the PPV oligomer molecular weight achieved 2500.According to IR and UVVis spectra,trans and synvinylene structures were its structural character.UVVis spectra shows λmax=497nm.
