  Tuning colorful luminescence of iridium(III) complexes from blue to near infrared

  摘要：

  Five cyclometalated Ir(III) complexes with high phosphorescence efficiencies have been synthesized from 1,3-bis (1-propyl-1H-benzo[d] imidazol-2-yl)benzene (Pro-MBImB) or 2-(2,4-Difluorophenyl)pyridine (Fppy) based ligands with different ancillary ligands. It was found that these complexes have a wide range of emitting wavelength, covering the whole visible region, with moderately long lifetime (81-2159 ns) and high quantum yield (75-89%). Especially, the introduction of electron withdrawing - COOEt group onto the ancillary ligand extends the emission wavelength and affords good red-light emitting properties, and the obtained CIE (Commission Internationale de L'Eclairage) coordinates of (0.69, 0.31) in complex 2 are close to the standard red light and approaching near infrared region.

  Provided is a process for preparing oligomers from an alkane. The process comprises (a) contacting an alkane under dehydrogenation conditions in the presence of a dehydrogenation catalyst such as an iridium catalyst complex comprising iridium complexed with a benzimidiazolyl-containing ligand to form olefins, and (b) contacting the olefins prepared in step (a) under oligomerization conditions with an oligomerization catalyst such as a nickel, platinum or palladium metal catalyst complex comprising the metal complexed with a nitrogen containing bi- or tridentate ligand to prepare oligomers of the olefins, and hydrogenating the olefin oligomers. In one embodiment, the ligands of the catalyst complexes in step (a) and step (b) can be the same.

  提供了一种从烷烃制备寡聚物的方法。该方法包括(a)在脱氢催化剂的存在下，在脱氢条件下接触烷烃，例如与苯并咪唑基含配体络合的铱催化剂复合物，以形成烯烃；(b)在寡聚化条件下接触步骤(a)中制备的烯烃，使用镍、铂或钯金属催化剂复合物，该金属与含氮的双或三齿配体络合，以制备烯烃的寡聚物，并对烯烃寡聚物进行氢化。在一个实施方案中，步骤(a)和步骤(b)中的催化剂复合物的配体可以是相同的。
