摘要: 以-甲基-2-氯甲基苯并(口恶)唑和对二苯甲醛为主要原料,通过两次Wittig-Horner反应,合成了未见文献报道的主链含有苯并-NFDA1-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 C=C 双键均为反式结构特征.UV-Vis吸收光谱特征峰λmax等于497 nm.

关键词: PPV齐聚物, 苯并噁唑, 合成

Abstract: A new PPV oligomer containing electron rich benzoxazole,which can enhance the electron transporting in PPV main chain,had been synthesized from 2-chloromethylbenzoxazole and p-phthalaldehyde by Wittig Horner reaction.The analytic data indicated that the PPV oligomer molecular weight achieved 2500.According to IR and UV Vis spectra,trans- and syn-vinylene structures were its structural character.UV-Vis spectra shows λmax =497nm.

Key words: PPV oligomer, benzoxazole, synthesis
