　　本論文以Colon的方法合成兩種聚對苯基共軛高分子衍生物，並進一步探討其光學性質、能量轉移現象與自組裝行為。
　　
　　將methyl 2,5-dichlorobenzoate單體置入nickel(0)的催化系統進行聚合反應，可得到poly[2-(methoxycarbonyl)phenylene-1,4-diyl] (PMCPD)，而後把PMCPD水解可產生poly(2-carboxyphenylene-1,4-diyl) (PCPD)。首先，利用紫外/可見光光譜儀與螢光光譜儀搭配偏光板探討PMCPD薄膜之光學特性，發現其具有光偏振性質，偏振比為3.135 (在412 nm位置)，結構次序參數為0.014 (在323 nm位置)。接著，將PMCPD混摻綠色或紅色發光高分子製備固態薄膜，探討薄膜光學特性，發現PMCPD與綠色或紅色發光高分子會有明顯的能量轉移現象。最後，以自組裝的方法製作PCPD與帶電荷聚電解薄膜並探討其光學性質，發現PCPD與poly(allylamine hydrochloride)所形成的薄膜有較佳之光學特性。

　In this study, two poly(p-phenylene) derivatives were synthesized by Colon’s method. Their optical properties, energy transfer phenomena, and self-assembly behaviors were studied.
　
　Methyl 2,5-dichlorobenzoate was polymerized in a nickel(0) catalyst system to produce poly[2-(methoxycarbonyl)phenylene-1,4-diyl] (PMCPD). The hydrolysis of PMCPD yielded poly(2-carboxyphenylene-1,4-diyl) (PCPD). The optical properties of PMCPD thin films were investigated by ultraviolet/visible spectrometer and fluorescence spectrometer combined with polarizers. The results indicated PMCPD thin films emitted polarized light with polarization ratio of 3.135 at 412 nm and order parameter of 0.014 at 323 nm. Then, the solid films were prepared by blending PMCPD with green or red light emitting polymer (LEP). Energy transfer phenomena were enhanced with ratios of blending green or red LEPs increasing. Finally, thin films consisted of PCPD and charged polyelectrolyte were prepared by self-assembly method. PCPD/poly(allylamine hydrochloride) self-assembly films have better .optical properties than PCPD/poly(acrylic acid) self-assembly films.
