本論文主要以研究吡唑類之衍生物於光電材料上之應用。而吡唑類衍生物之合成係以雪梨酮為起始物進行1,3雙偶極環化加成反應而得到含吡唑環之化合物，進一步合成各類吡唑類衍生物，再將之應用於發光材料之領域。
本論文為研究小分子有機發光二極體之材料，材料之合成以雪梨酮為起始物進行衍生，合成出含有吡唑環與1,3,4-口咢二唑環之化合物，再進一步衍生出含有不同官能基之有機發光二極體材料。利用此類之設計合成出多種光電材料，並對其物理性質、化學性質、光電性質做深入之探討。
近來之期刊報導常見吡唑環與口咢二唑環之化合物被應用於光電材料上，因此，本研究除了採用上述兩種雜環官能基當做分子骨架，另外導入咔唑類之具有高熱穩定性之官能基，以提升分子結構之剛性，而高熱穩定性分子之小分子發光材料其優點在於真空熱蒸鍍時不易發生燒結之現象，且組成元件後之使用壽命也會有相對之提升。

In this study, I had synthesized a series of pyrazole derivatives, and applied in organic electro-luminescence devices. The series of pyrazole derivatives were all synthesized from sydnone via 1,3-dipolar cycloaddition.
Organic light-emitting diode (OLED) is a novel technology. The large size display can be made via this technology. Because of some organic materials have high fluorescence efficiency and semiconducting properties, they often applicable to
electro-luminescence (EL) devices. The other hand, the emission colors can be determine via modify organic compounds. Hence, the organic material plays a decisive role in OLED technology.
Compounds derived from 1,3,4-oxadiazoles had been reported having good electron-transporting properties and the pyrazole moiety is an electron-rich heterocycle. So we introduced 1,3,4-oxadiazoles into pyrazole derivatives. In order to improve thermostabilities and electro-luminescence properties, we introduced carcazole and phenyl into 1,3,4-oxadiazole-based pyrazole derivatives.
The physical 、 chemical and electro-luminescence properties were studied by DSC 、 UV-Vis 、 CV and PL spectra. The OLED device was constructed by vapor deposition of the materials under vacuum onto the ITO-coated glass substrate. The I-V curves and EL spectra had proven that our new synthetic compounds were new efficient blue electroluminescent materials.
