摘要 萘酰亚胺衍生物是一类发光效率优良的电子传输型电致发光材料。本文采用亲核取代反应将其作为聚合物主链的一部分构成主链含1,8-萘酰亚胺的聚芳醚型发光聚合物(PENI),聚合物的重均分子量为4 300。通过FT-IR和NMR对单体及聚合物的结构进行了鉴定,并研究了其光致发光性能和电化学性能。在分子量较小时,PENI薄膜的PL发射峰位于407,456,530 nm;当聚合物分子量提高后,发射峰红移14 nm左右。采用循环伏安法测得聚合物的HOMO和LUMO分别为-5.64 eV和-2.93 eV,Eg为2.71 eV。 A novel aromatic polyether with a 1,8-naphthalimide unit main chain(PENI) was synthesised by nucleophilic substitution reaction.The molecular weight of the polymer is 4 300.The structure of monomer and polymer were characterized by FT-IR and NMR,and photoluminescence and cyclic voltammetry of the PENI were also investigated.Along with the increasing of molecular weight,the emission of the PENI film red-shifted about 14 nm.The HOMO-LUMO and energy gap(Eg) of PENI was about-5.64/-2.93,2.71 eV,respectively.
