以2-甲基苯并噻唑、苯甲醛为原料,通过与三氯化铱配合,得到一种新型红色金属铱(Ⅲ) E-2-苯乙烯基苯并噻唑(SBT)乙酰丙酮(acac)配合物(SBT)2Ir(acac).通过质谱、核磁、红外光谱对其结构进行了表征,并对其光致发光性能进行了研究.研究结果表明:配合物(SBT)2 Ir(acac)在428和471nm处的紫外吸收属于单线态和三线态金属铱到配体的电荷转移吸收(1MLCT和3MLCT);在632nm处有强的金属配合物三线态磷光发射;(SBT)2Ir(acac)金属配合物的EHOMO=-4.8 eV,ELUMO=-2.5eV,磷光量子效率Φ (SBT)2Ir(acac) =0.19.(SBT)2Ir(acac)可能是一种极有潜力的电致磷光材料.

A new red phosphorescent, (E)-2-styrylbenzothiazole (SBT) iridium(Ⅲ) acetylacetone(acac) complex (SBT)2Ir(acac), was synthesized from 2-methylbenzothiazole, benzaldehyde and iridium trichloride anhydrate. The com-plex was characterized by MS, 1H-NMR and FT-IR. The complex showed singlet and triplet metal to ligand charge-transfer (1MLCT and 3MLCT)at 428 and 471nm. The complex also gaves a photoluminescence at 632nm, EHOMO = - 4. 8eV , ELUMO = -2. 5eV and phosphorescent quantum yield Φ (SBT)2Ir(acac) =0. 19. The complex (SBT)2Ir(acac) may be a promising electrophosphorescent material.
