本論文合成了兩系列的imidazole化合物，在imidazole接上benzilic halide形成有非共軛系統取代基的配位基，這些化合物可以與三氯化銥以cyclometalation的形式形成具有強磷光性質的銥金屬化合物，而這兩系列與三氯化銥形成分子型和離子型兩種系列的化合物。而最主要是改變benzilic halide上的官能基去探討非共軛系統的推拉電子基對磷光銥金屬化合的的光物理性質影響。
而在分子型(acac型)部分，銥除了與imidazole配位外同時也會與acac配位而形成六配位的化合物[Ir(ŋ2-C^N)2acac]，依不同的C^N配位基，合成出的acac型金屬化合物有Ba,2Fa,3Fa,4Fa,2Cla,3Cla,
4Cla,3omea,pFa,Ha等十種，光物理性質方面，在二氯甲烷中依官能基不同造成波長變化可從507nm到517nm，量子產率則在0.38到0.54之間，而固態放光的波長在542nm到551nm。
在離子型(L型)方面，銥與兩個ppy配位跟用imidazole跟benzylhalide合成出來的含非共軛系統配位基共形成六配位的[Ir(ŋ2-ppy)2L2]NO3，依不同的L配位基，合成出的L型金屬化合物有BL,2FL,3FL,4FL,4ClL,3omeL,pFL,HL等八種，光物理性質方面，在二氯甲烷中依官能基不同造成波長變化可從484nm到488nm，量子產率則在0.30到0.37之間，而固態放光的波長在518nm到522nm。
所有錯合物均用質譜，IR，NMR光譜進行鑑定，其中4Fa、2Cla、3Cla、4Cla、4ClL、BL、HL也進一步得到晶體結構。

We have synthesized two series of imidazole compounds, that added benzilic halide to form ligands containing non-conjugated substituents. These compounds undergo cyclometalation with iridium trichloride to form iridium (III) complexes which exhibit strong phosphorescence. These two series of imidazole compounds combined with iridium trichloride to form two types of iridium complexes, neutral-type and ion-type. We changed substituents on the benzilic hailide to investigate the photophysical effect of non-conjugated electron-donating and electron-withdrawing groups.
In neutral-type(acac-type), iridium trichloride undergo cyclometalation with imidazole and acac to form six-coordinated complexes [Ir(ŋ2-C^N)2acac]. According to different C^N ligands, we synthesized ten kinds of metal complexes, Ba, 2Fa, 3Fa, 4Fa, 2Cla, 3Cla, 4Cla, 3omea, pFa, Ha. The emission wavelengths range from 507nm to 517nm and quantum yields range from 0.38 to 0.54 in CH2Cl2 solution. The solid state emission wavelengths range from 542 nm to 551nm.
In ion-type(L-type), iridium trichloride undergo cyclomatalation with ppy and imidazole compounds to form six-coordinated complexes[Ir(ŋ2-ppy)2L2]NO3. According to different L, L’ ligands, we synthesized eight kinds of metal complexes, BL, 2FL, 3FL, 4FL, 4ClL, 3omeL, pFL, HL. The emission wavelengths range from 484nm to 488nm and quantum yields range from 0.30 to 0.37.The solid state emission wavelengths range from 518nm to 522nm.
All compounds have been characterized by Mass, IR, NMR spectroscopy. Compounds 4Fa, 2Cla, 3Cla, 4Cla, 4ClL, BL, HL have been further collecting the respective X-ray diffraction data and solved for the solid state structure.
