The preparation of the first enantiopure cycloplatinated complexes bearing a bidentate, helicenic N-heterocyclic carbene and a diketonate ancillary ligand is presented, along with their structural and spectroscopic characterization based on both experimental and computational studies. The systems exhibit long-lived circularly polarized phosphorescence in solution and in doped films at room temperature, and also in a frozen glass at 77 K, with dissymmetry factor values ≥10 in the former and around 10 in the latter.
本文介绍了首例手性环金属铂配合物的制备,该配合物含有双齿、螺旋型 N-杂环卡宾和二酮配体,并基于实验和计算研究对其结构和光谱特性进行了表征。这些体系在溶液中和掺杂薄膜中在室温下以及在 77 K 的冷冻玻璃中都表现出长寿命的圆偏振磷光,前者的不对称因子值≥10,后者约为 10。
