本論文中主要以Heck reaction 聚合反應，將1,3,4-二唑環導入主鏈中，並進一步的將雪梨酮做衍生合成兼具含有唑官能基的高分子發光材料。藉由這樣的設計並深入的探討高分子材料之結構，物性及光電性質。
　　合成之高分子對一般有機溶劑有良好的溶解度，並由DSC分析可顯示出高分子P3~P6 有較高的Tg在149°C ~ 167 °C之間，在使用於發光材料時較不會減短元件的壽命。合成的高分子有很好的穩定性，在氮氣之下其熱裂解溫度在260°C以上，而至800°C除了P1 以外皆有不錯的剩餘率約28% ~ 35%之間。UV-Vis光譜中出現了三個吸收峰，分別為主鏈共軛的π—π*、二唑基團和苯環的吸收。在溶劑中的PL螢光放光波長為藍綠光到黃光，成膜態的PL則表現出綠光到橙光其最大放光波長範圍為485 ~ 573 nm。合成之高分子的譜帶間隙為2.32~2.54 eV，而LUMO的電位估計在2.44~2.81eV。由循環伏安法(CV)得知增加一組高陰電性的二唑基團和唑基團可以降低HOMO及LUMO的能階，對於元件的電子電洞注入速率不均勻有些許的幫助。

　Six poly(p-phenylenevinylene) derivatives, P1~P2 with oxadiazole along the main chain and P3~P6 bearing two 1,3,4-oxadiazole rings and pyrazole rings from sydnone along the main chain were synthesized via Heck coupling. The new polymer are studied on their structure,physical and photoelectronic properties.
　The polymers dissolved readily in common organic solvents and had high glass-transition temperature values of 149°C ~ 167 °C for P3 ~P6.They were stable up to approximately 260°C ~ 350°C in N2 and the anaerobic char yield was around 28 ~ 35% at 800 °C except P1. UV-Vis spectra show three peaks at 374 ~ 410 nm ,296~344 nm and 240 nm that correspond to the π-π* transition of the conjugated polymer backbone, oxadiazole and aromatic, respectively. They emitted greenish- blue or yellow light in solution and emitted green or orange light with PL emission maxima at 485 ~ 573 nm. The energy gap and electron affinity of the polymers were estimated as 2.32~2.54 eV and 2.44~2.81eV, respectively. Electrochemical behavior of the polymers demonstrates that introducing the high electron affinity oxadiazole moiety and pyrazole into the backbone lowers both the HOMO and LUMO energy levels of the polymers, thus mitigating the problem of charge injection imbalance in polymer LEDs.
