  C^∧C* Cyclometalated Platinum(II) Complexes with Dibenzofuranyl-1,2,4-triazol-5-ylidene Ligands: Synthesis, Characterization, and Photoluminescent Properties

  摘要：

  Two series of new platinum(II) NHC complexes with C<^>C* cyclometalating 1-(dibenzo[b,d]furan-4-yl)-4-methyl-1H-1,2,4-triazole and 1-(dibenzo[b,d]furan-2-yl)-4-methyl-1H-1,2,4-triazole ligands and several beta-diketonato auxiliary ligands (acetylacetonato, dibenzoylmethanato, and dimesitoylmethanato) were synthesized, characterized (NMR spectroscopy, elemental analysis, and X-ray crystallography for two complexes) and investigated in terms of their photoluminescence properties. All complexes are strongly emissive at room temperature in a 2 wt % complex doped poly(methyl methacrylate) film at room temperature. Using dibenzoylmethanato as auxiliary ligand leads to a broad emssion band with a maximum in the green region of the spectrum, whereas the complexes with acetylacetonato and dimesitoylmethanato ligands reveal structured blue emissions with wavelengths that strongly depend on the arrangement of the dibenzo[b,d]furan (DBF) unit.

  Novel iridium complexes containing triazole and tetrazole carbene ligands are described. These metal complexes additionally contain dibenzo moieties such as dibenzothiophene and dibenzofuran, and the complexes have overall improved properties such as more saturated blue emission when used as emissive compounds in OLED devices.

  描述了含有三唑和四唑卡宾配体的新型铱配合物。这些金属配合物还含有二苯并噻吩和二苯并呋喃等二苯并基团，并且当作发光化合物在OLED器件中使用时，这些配合物具有更饱和的蓝色发射等改进性能。
