crossing the spectrum of visible light. Most of the Pt complexes are strongly luminescent (Φ = 0.32−0.63) and have short luminescence lifetimes (τ = 4−7 μs) at room temperature. The lowest excited state of the Pt(N∧C∧N)X complexes is identified as a dominant ligand-centered 3π−π* state with some 1MLCT/3MLCT character, which appears to have a larger 1MLCT component than their bidentate and tridentate analogs

We report the synthesis, electrochemistry, photophysical properties and electroluminescence of a highly luminescent pyrazolate-bridged platinum(II) complex. The complex has the general formula of [((N^C^N)Pt)2(μ-pz)][PF6] where N^C^N = 1,3-di(2-pyridyl)benzene and μ-pz = 3,5-diphenylpyrazolate. The X-ray structure shows that the bridging pyrazolate ligand causes a close Pt–Pt interaction of 3.05(7)
我们报告了合成,电化学,光物理性质和电致发光的高度发光的吡唑酸酯桥铂(II)复杂。该络合物的通式为[[((N ^ C ^ N)Pt)2(μ-pz)] [PF 6],其中N = C = N = 1,3-二(2-吡啶基)苯,μ-pz= 3,5-二苯基吡唑酸酯。X射线结构表明,桥连的吡唑酸酯配体引起3.05(7)Å的紧密Pt-Pt相互作用。在溶液,77 K的玻璃状2-甲基四氢呋喃和室温及77 K的固态下测定了络合物的发射曲线。在溶液中,每种发射曲线均显示出很强的红色金属-金属-配体电荷转移玻璃态的2-甲基四氢呋喃的发射曲线也显示出以配体为中心的跃迁。溶液和室温下固态的复合物的绝对量子产率分别为86%和39%。[((N ^ C ^ N)Pt)2(μ-pz)] [PF 6的发光电化学电池(LEEC)在迄今为止最亮,最高效的双核化合物LEEC中,制造了可显示出可观电致发光的化合物。
Concentration-dependent circularly polarized luminescence of chiral cyclometalated platinum(II) complexes for electroluminescence
acetonitrile solution. However, when the complexes were doped into polymethyl methacrylate, the green emission originated from intrinsic single molecule can be changed to the red emission from excimer by adjusting the doping ratios. More importantly, the amplification of CPL signal can be achieved compared with the solution state. Furthermore, the monochrome devices were fabricated by utilizing these two enantiomers

dependence of the reactions. Two crystal structures of [Pt(N-N-C)Cl] were determined (yellow and red polymorphs); the intense red color of the latter polymorph results from Pt-Pt interactions (Pt-Pt distance = 3.366 A). The data enable an analysis of the cis and trans effects and the influence of the strong sigma-donor carbon in the presence of an electron withdrawing pi-acceptor ligand backbone. The results
