摘要

聚对苯（ＰＰＰ）作为一个具有良好特性的导电聚合物材料很早便受到人们的青睐．进入九十年代后

它作为一种蓝色电致发光材料又受到人们的普遍注意．１９９２年

Ｇｒｅｍ等［１］采用Ｂａｌａｒｄ前驱聚合物法合成了ＰＰＰ并成功地用其制成了发光器件．１９９５年

他们再一次报道了使用低分子量的ＰＰＰ及其不溶性的衍生物制备的器件［２］．同年

Ｈａｍａｇｕｃｈｉ等［３］使用可溶性的庚氧基取代ＰＰＰ制备的蓝色电致发?...

Abstract

A series of blue luminescent materials poly(2

5-dialkoxyphenylene)(AO-PPP)which were soluble in common organic solvents were prepared by Scholl reaction.The UV-Vis spectrum and photoluminescence(PL)spectrum were studied.The UV-Vis spectrum of AO-PPP exhibit two absorption bands E1 band(short wavelength absorption)and E2 band(long wavelength absorption)which is similar with that of polyphenylene(PPP).The E1 band dont change with increasing of the length of side chain and locates at 242nm

but the E2 band occurs blue shift continuously and splits when the side chain is dodecyloxy ortetradecyloxy. The change of the PL spectrum is also regularly with the increasing of the length of the side chain. The largest emitting peak occur at 400nm when the number of the carbon atom of the side chain equals or is larger than 8.
