摘　　要：本研究将传统的2-苯基吡啶配体进行改性,用富电子的噻吩基团代替苯基,得到有机配体2-噻吩基吡啶(L1),并以L1合成铱(Ⅲ)配合物C1,而基于2-苯基吡啶(L2)配体的铱(Ⅲ)配合物C2也被合成得到,以用做性质对比;随后通过质谱(MS)、核磁共振谱(NMR)以及傅里叶变换红外光谱(FT-IR)对产物C1和C2进行结构表征,并利用紫外可见光吸收光谱(UV-Vis)以及光致发光光谱(PL)等测试手段,对比C1与C2的光谱性质,利用噻吩基代替苯基后,UV-Vis的吸收范围扩大,PL的最大发射峰发生了红移。The research modified the traditional 2-phenylpyridine ligand,replaced the phenyl group with electron-rich thienyl group,to obtain the 2-(2-thienyl)pyridine ligand(L1),then synthesized the iridium(Ⅲ)complex(C1)with this ligand,and the iridium(Ⅲ)complex C2 was synthesized with 2-phenylpyridine ligand(L2)for the comparison.After the structure characterization by NMR,MS and FT-IR,the target products C1 and C2 had been characterized by UV-Vis and PL as photophysical properties contradistinction,we found that the absorption of C1’s UV-Vis spectrum had been extended and the maximum emission peak of C1 had red-shifted after the replacement of thenyl group with phenyl group.
