Synthesis and Photophysical Properties of Red-Emitting Iridium （Ⅲ） Complex Bearing Benzothiazole

Abstract:

New red phosphorescent material, (E)-2-(2-(thiophen-2-yl) vinyl)benzothiazole(2THSBT) iridium(III) acetylacetone(acac) complex [(2THSBT)₂Ir(acac)] is synthesized from 2-methyl benzothiazole, thiophene-2-carbaldehyde and iridium trichloride anhydrate. The complex is characterized by MS and 1H-NMR. (2THSBT)₂Ir(acac) gives a photoluminescence at 687nm, phosphorescent quantum yield: Φ_{(2THSBT)₂Ir(acac)}=0.2 and EHOMO = -4.8 eV, ELUMO = -2.6eV, respectively. The complex may be a promising electrophosphorescent material.
