Cyclometalated Ir(III) complexes with pyrenyl-fused imidazole ligands were prepared. The complexes show strong absorption of visible light and long-livedtripletexcitedstate and were used as triplet photosensitizers for triplet–triplet annihilation (TTA) upconversion. Pyreno[4,5-d]imidazole C^N ligand was used to access the long-lived T1 excitedstate (Ir-1, bpy = 2,2′-bipyridine as the N^N ligand

of the diimine ligand (N^N ligand) via benzannulation is a common way to tune the absorption and emission energies of cationic iridium(III) complexes. However, it can cause either a red- or blue-shift of the absorption and emission bands depending on the site of benzannulation. To understand the mechanism of changes in optical transitions upon benzannulation on the diimine ligand, a series of new cationic
通过苯环扩大二亚胺配体(N ^ N配体)的π-共轭是调节阳离子铱(III)配合物的吸收和发射能的常用方法。但是,根据苯环的位置,它可能导致吸收带和发射带发生红移或蓝移。为了理解上的二亚胺配体,一系列新的阳离子铱(III)配合物在苯并环化在光学跃迁变化的机构的[Ir(DPPI)2(N ^ N)] PF 6(1 - 6)(其中DPPI = 1 ,2-二苯基吡喃并[4,5- d ]咪唑; N ^ N = 2-(吡啶-2-基)喹啉(1),2-(吡啶-2-基)[7,8]苯并喹啉(2), 2,2'-双喹啉(3),2-(喹啉-2-基)[7,8]苯并喹啉(4),2-(吡啶-2-基)[6,7]苯并喹啉(5),2-(喹啉-2-基)[合成了包含二亚胺配体的6,7]苯并喹啉(6),该二亚胺配体在2-(吡啶-2-基)喹啉配体的不同位点通过苯环化具有不同的π-共轭度。实验结果和密度泛函理论(DFT)计算表明,苯并环化在喹啉的6
