We have prepared poly(2,5-dimethoxy-1,4-phenylenevinylene) (DMEOPPV) and poly(2,5-thienylenevinylene)
(PTV)
via xanthate precursor polymer routes. The respective precursor polymers can be thermally converted to their corresponding conjugated polymers without the need for acid catalysis. For both DMEOPPV and PTV the UV-visible absorption and infrared spectra were similar to the polymers when prepared via alkoxy precursors. Films of DMEOPPV and blends of DMEOPPV and PPV were found to be luminescent with energy being transferred from the PPV host to the DMEOPPV guest. Films of PTV or PTVâPPV blends were found not to be luminescent.
我们通过黄原酸盐前体聚合物路线制备了聚(2,5-二甲氧基-1,4-苯基乙烯)(DMEOPPV)和聚(2,5-噻吩乙烯)(PTV)。相应的前体聚合物无需酸催化即可热转化为相应的共轭聚合物。DMEOPPV 和 PTV 的紫外可见吸收光谱和红外光谱与通过烷氧基前体制备的聚合物相似。研究发现,DMEOPPV 薄膜以及 DMEOPPV 和 PPV 的混合物具有发光特性,能量从 PPV 主体传递到 DMEOPPV 客体。而 PTV 或 PTVâPPV 混合物薄膜则不发光。
