| 摘 要： | 以水合三氯化铱为原料,2-(对甲苯基)吡啶作环金属配体、乙酰丙酮作辅助配体合成了双2-(对甲苯基)吡啶]乙酰丙酮合铱(tpy)2Ir(acac)],通过质谱、氢谱、X射线单晶衍射分析表征手段确证了其分子结构。通过紫外可见光谱和光致发光光谱分析,研究了该配合物的光物理性能,在410和461 nm处有单重态和三重态吸收,在516 nm处有较强的绿光发射,表明该配合物是一种绿光材料。

| Abstract: | (tpy)2Ir(acac) was synthesized by the reactions of iridium chloride hydrate as the raw material, 2-(p-tolyl)pyridine as the cyclometallated ligand and acetylacetone as the auxiliary ligand, and the resulting complex was characterized by MS, 1H-NMR and single crystalline XRD. The absorption and emission spectra of the complex were measured to evaluate its photophysical properties. 1MLCT and 3MLCT absorptions occured at 410 and 461 nm, respectively, and a stronger photoluminescence appeared at 516 nm, indicating that this complex is a green material. |
