摘要：

合成两种含双键的铱配合物磷光材料Ir(ppy)₂(ADP) (ADP=1，3-二苯基-2-烯丙基-1,3-丙二酮, ppy=2-苯基吡啶), Ir(ppy)₂(VPHD) (VPHD=6-对乙烯基苯基-2，4-己二酮).与铱配合物Ir(ppy)₂(acac) (acac=2,4-戊二酮)的光谱数据比较， Ir(ppy)₂(VPHD)具有相似的磷光光谱，最强发射波长为520 nm，发射强的绿色磷光.Ir(ppy)₂(ADP)配合物的磷光光谱随测试样品浓度的变化而变化，且发光较弱.这是由于ADP配体中两个苯环的引入，使配合物的发光波长明显向短波长方向移动，且发光效率降低.该结果为合成新的磷光材料提供了参考依据.

Abstract:

Two iridium complexes, Ir(ppy)₂(ADP) (ADP=2-allyl-1,3-diphenyl-1,3-propanedione, ppy=2-phenyl-pyridine), Ir(ppy)₂(VPHD) (VPHD=6-(4-vinylphenyl)-2,4-hexanedione), have been synthesized and characterized by ¹H-NMR and FTIR. Compared with spectra of the reported iridium complex Ir(ppy)₂(acac) (acac=2,4-acetylacetone), Ir(ppy)₂(VPHD) and Ir(ppy)₂(acac) have the similar phosphorescence spectra, and their excellent green luminescence were observed with the maximum emission wavelengh at 520 nm. The maximum emission wavelengh for the Ir(ppy)₂(ADP) in ethyl acetate solutions changed with its concentrations, from 487 nm (10^-5mol·L^-1) to 516 nm (10^-4mol·L^-1). The maximum emission bands for the Ir(ppy)₂(ADP) shifted to shorter wavelengths compared with those of the other two Ir³⁺complexes.
