【摘要】 本文合成了一种中性的铱配合物[Ir(ppy)2(PPh3)(NCO)],并通过红外、核磁、电喷雾离子质谱和元素分析等对其进行了表征。通过X射线衍射确定了该配合物的晶体结构,该配合物晶体属于单斜晶系,空间群为P21/c。其中a=0.99447(4)nm,b=1.48082(6)nm,c=2.24713(11)nm,β=101.183(2)°,V=3.2464(2)nm3,Z=4,Dc=1.647g·cm-3,F(000)=1592,R1=0.0328,wR2=0.0987(I>2σ(I))。光致发光光谱表明,该配合物在二氯甲烷、氯仿和DMF中的最大发射波长分别为485,484和515nm,即在二氯甲烷和氯仿中发蓝绿光,在DMF中发绿光。在强极性溶剂中,化合物的磷光最大发射波长发生了红移。更多还原

【Abstract】 A neutral Iridium (Ⅲ) complex [Ir(ppy)2(PPh3)(NCO)] has been synthesized and characterized by IR, 1H NMR, ESI mass spectra and elemental analysis. The crystal structure of the complex has been determined by X-ray analysis. The compound crystallizes in monoclinic, space group P21/c with a=0.994 47(4) nm, b=1.480 82(6) nm, c=2.247 13(11) nm, β=101.183(2)°, V=3.246 4(2) nm3, Z=4, Dc=1.647 g·cm-3, F(000)=1 592, R1=0.032 8 and wR2=0.098 7 (I>2σ(I)). The photoluminescence (PL) spectra of the complex in dichloromethane, chloroform and dimethylfomamide (DMF) show emission maxima at 485, 484 and 515 nm, respectively, corresponding to blue-green light-emitting in dichloromethane and chloroform, green light-emitting in DMF. The results show that the PL maxima have red shifted in strong polar solvent. CCDC: 738942.更多还原
