分别以2-苯基吡啶(ppy)和2-(对甲苯基)吡啶(ptpy)为配体,与三水合氯化铱(IrCl3.H2O)、3-(4-甲基)苯乙烯-2,4-戊二酮(MSPD)配位,得到铱(Ⅲ)配位物Ir(ppy)2(MSPD)和Ir(ptpy)2(MSPD).通过元素分析、FTIR光谱、1H NMR对其进行了结构表征,此外还研究了其吸收光谱和光致发光光谱,结果表明:配位物Ir(ptpy)2(MSPD)和Ir(ppy)2(MSPD)均具有明显的金属-配体电荷转移吸收(MLCT),且分别在522 nm、530 nm处有较强的金属配合物三重态的磷光发射峰,有望在电致发光方面得到应用.

Ir(ptpy)2(MSPD)and Ir(ppy)2(MSPD) are synthesized by the reaction of two ligands 2-phenylpyridine and 2-(p-Tolyl) pyridine,compounded with IrCl3 and MSPD.The structures of the complexes are characterized through elemental analyses,FTIR,and1H NMR.The UV-Vis absorption and photolum inescence(PL) spectra of the complexes are investigated.The two Ir complexes show the noticeable MLCT absorption(singlet and triplet metal to ligand charge transfer absorption),and have strong photolum inescence at 522 nm and 530 nm,respectively.The test results indicate that they can be applied in the field of OLED.
