Synthesis and Photophysical Properties of Iridium(III) Complex with Cyclometalated Styrylbenzothiazole Ligand
Abstract:
New red phosphorescent material, (E)-2-(4-fluorostyryl) benzo [d] thiazole (4-FSBT) iridium (III) dibenzoylmethane (DBM) complex [(4-FSBT)2Ir (DBM)] is synthesized from 2-methyl benzothiazole, 4-fluorobenzaldehyde, iridium trichloride anhydrate and DBM. The complex is characterized by MS and 1H-NMR. (4-FSBT)2Ir (DBM) gives a photoluminescence at 625.8nm, phosphorescent quantum yield: Φ(4-FSBT)2Ir (DBM) = 0.2 and EHOMO = -4.7 eV, ELUMO = -2.5eV, respectively. The complex may be a promising electrophosphorescent material.
