| 摘要: 以2-（2-吡啶基）苯并噻吩（2-（2-pyridyl）benzothiophene，btp）作为主配体，分别以邻二氮菲[1，10]并咪唑联苯酚（2-（1H-imidazo[4，5-f][1，10]phenanthrolin-2-yl）phenol，ipap）和3-甲基-6-苯基咪唑[2，1-b]噻唑（3-Methyl-6-phenylimidazo[2，1-b]thiazole，mpmt）作为辅助配体，成功合成了2个二价铂配合物[（btp）Pt（ipap）]Cl与（btp）Pt（mpmt）Cl，并得到了配合物（btp）Pt（mpmt）Cl的晶体结构。由金属-配体电荷转移引起的2种配合物发光，具有60%左右的内量子效率，发射峰在426 nm（蓝色）与381 nm（紫色）处。HOMO/LUMO轨道能级分别为-4.69 eV/-2.55 eV与-4.80 eV/-2.21 eV。单晶衍射结果表明，较低的共轭程度导致了该类配合物的短波长发射。 | |

| Abstract: With 2-(2-pyridyl)benzothiophene (btp) as the primary ligand, 2-(1H-imidazo[4,5-f] [1,10]phenanthrolin-2 -yl)phenol (ipap) and 3-methyl-6-phenylimidazo[2,1-b]thiazole (mpmt) as the auxiliary ligands, two platinum(Ⅱ) complexes,[(btp)Pt(ipap)]Cl and (btp)Pt(mpmt)Cl were synthesized, and the crystal structure of (btp)Pt(mpmt)Cl was determined. The luminescence of the complexes which is attributed to the metal-to-ligand charge transfer (MLCT) emission has internal quantum efficiency about 60% with emission peaks at 426 nm (blue) and 381 nm (purple). The orbital energy levels of HOMO/LUMO were -4.69 eV/-2.55 eV and -4.80 eV/-2.21 eV, respectively. The crystal structure discloses that the low conjugation of these complexes results in their short wavelength emission. CCDC:1978721, (btp)Pt(mpmt)Cl. | |
