本研究已成功的運用原子轉移自由基聚合法(ATRP)，來獲得狹分子量分佈的側鏈型螢光高分子(PMMAPBO及PMMAPBT)，其放光波長分別為400 nm及430 nm。螢光單體是以親核取代的方式，將螢光材料2-(2’-hydroxyphenyl)benzoazole (o-OHPBO)或2-(2’-hydroxyphenyl)benzothiazole (o-OHPBT)，導入乙烯系衍生物。此單體再以ATRP之乳化聚合法，與甲基丙烯酸甲酯共聚，獲得一側鏈型螢光高分子，並以凝膠層析鑑定分子量及分子量分佈。
電激發光元件方面，我們是以PVK摻雜o-OHPBT的方式，獲得發白光元件，其放光光譜由三個波峰組成，其波長分別為415nm、525nm及600nm，起始電壓為8伏特。當我們將o-OHPBT摻入PVK/Alq3元件，可以得到一綠光電激發光元件，其元件有高發光強度及降低元件的起始電壓。

In this study, the synthesis of benzoazole contained fluorescent pendent polymers (PMMAPBO and PMMAPBT) with narrow molecular weight distribution is presented. The benzoazole contained fluorescent monomer are synthesized from 2-(2’-hydroxyphenyl)benzoxazole and methacryloyl chloride by the nucleophilic substitution reaction. The polymerization is carried out by the atom transfer radical polymerization methodology. The polymers exhibited deep blue fluorescent with the PL λmax at 400 nm for PMMAPBO and 430 nm for PMMAPBT.
The benzoazole contained fluorescent dye, OHPBT, is found useful to fabricate white-light electroluminescent devices using PVK as polymer matrix. This polymer blended EL device has relatively low driving voltage at 8 Volts. The EL spectrum exhibits three emission peaks at 415, 525 and 600 nm, which represent deep blue, green and red.
