  摘要：

  A series of new fac-triscyclometallated iridium complexes Ir(Ln)(3) (n = 1-6) (L-1: 2-{4-[5-phenyl-[1,3,4] oxadiazol-2-yl]-phenyl}-pyridine, L2: 2-{4-[5-(4-tert-butyl-phenyl)-[1,3,4] oxadiazol-2-yl]-phenyl}pyridine, L3: 9-(4-pyridin-2-yl-phenyl)-9H-carbazole, L4: 1-[4-(5-phenyl-[1,3,4] oxadiazol-2-yl)-phenyl]- isoquinoline, L5: 1-{4-[5-(4-tert-butyl-phenyl)-[1,3,4] oxadiazol-2-yl]-phenyl}-isoquinoline, L6: 9-(4-isoquinolin-1-yl-phenyl)-9H-carbazole) based on Ir(ppy)(3) (ppy = phenyl-pyridine) and Ir(piq)(3) (piq = 1-phenylisoquinoline) were synthesized from Ir(acac)(3) and corresponding ligands by a new and effective way using anthracene as a solvent. Single-crystal X-ray diffraction spectra of three complexes were studied and the iridium centers were found to adopt distorted octahedral coordination geometry. UV-Vis, photoluminescence, cyclic voltammetry were employed for studying the photophysical and electrochemical properties. These complexes exhibit intense phosphorescence in toluene solution at room temperature with high quantum efficiencies (0.07-0.58) and submicrosecond lifetimes (0.57-0.87 mu s).

• Novel Method of Synthesizing Various Five Membered Heterocycles from an Aryl Tribromomethyl Group
  作者：Robert Tynebor、Elizabeth Millings

  日期：2013.7.18

  Synthesis of five membered heterocycles from an aryl tribromomethyl functional group is discussed. Exposing a tribromomethyl group to subsequent nucleophilic attacks by a 1,2-di-nucleophilic species promotes the cyclization of five membered heterocycles. Such heterocycles as oxadiazoles, thiadiazole, benzimidazole, benzothioazole, and benzoxazole were synthesized in moderate to good yields. Supplemental materials are available for this article.
