Herein we report the synthesis and photophysical study of tris-heteroleptic complexes of the general formula IrLL'(acac), where L and L' are two differently substituted 2-phenylpyridines (ppyH) and acacH is 2,4-pentanedione, using a combinatorial approach that could be employed for many ligand combinations. The tris-heteroleptic complexes and the analogous bis-heteroleptic complexes of the form IrL(2)(acac) have been studied by a combination of absorption and photoluminescence spectroscopies in conjunction with modelling by DFT and TD-DFT to elucidate the nature and location of the excited state in the novel species.
在此，我们报告了通用式 IrLL'（acac）的三杂化配合物的合成和光物理研究，其中 L 和 L'是两种不同取代的 2-苯基吡啶（ppyH）和 acacH 是 2,4-戊二酮，使用了一种组合方法，可用于许多配体组合。通过吸收和荧光光谱学的组合以及 DFT 和 TD-DFT 的建模，研究了三杂化配合物和类似的 IrL(2)(acac)的双杂化配合物，以阐明新型物种中激发态的性质和位置。
