摘要

Two new iridium(III) complexes containing benzothiazol-2-yl carbazole derivative as a cyclometalated ligand (L) and picolinate (pic) or acetylacetonate (acac) as the ancillary ligand, Ir(III) bis(3-(benzothiazol-2-yl)-9-butyl-carbazole) (picolinate) [Ir(L)2(pic)] and Ir(III) bis(3-(benzothiazol-2-yl)-9-butyl-carbazole) (acetylacetonate) [Ir(L)2(acac)], were synthesized and characterized by elemental analysis, 1H NMR, FT-IR, and UV-Vis absorption spectra. Both the iridium(III) complexes emit intense green-yellow emissions, indicating that they are useful for the fabrication of organic light-emitting diodes.
