| 中文摘要 | four new iridium(iii) complexes 1-4, with 1,3,4-oxadiazole derivative as cyclometalated ligand for the first time, have been synthesized and structurally characterized by nmr, ea, ms and x-ray diffraction analysis (except 1). the stronger ligand field strength of the dithiolate ancillary ligands results in higher oxidation potentials and lower homo energy levels of complexes than acetylacetone. the absorption spectra of these complexes display low-energy metal-to-ligand charge transfer transition ranging from 350 to 500 nm. complexes with dithiolate ancillary ligand emit at maximum wavelengths of ca. 500 nm, blue shifting 17 and 11 nm with respect to their counterpart with acetylacetone ligand. the electrophosphorescent devices with 2-4 as phosphorescent dopant in emitting layer have been fabricated. all devices have a low turn-on voltage in the range of 4.5 and 4.9 v. a high-efficiency green emission with maximum luminous efficiency of 5.28 cd/a at current density of 1.37 ma/cm(2) and a maximum brightness of 2592 cd/m(2) at 15.2 v has been achieved in device using 2 as emitter. |
