synthesis of phosphole-modified aza[6]helicenes and the complexation of these pi-conjugated ditopic ligands with metallic ions are described. The chiroptical properties of these metal-bis(helicene) assemblies were experimentally evaluated and studied by first-principles theoretical calculations. The results show that the metal impacts the chiroptical properties of these complexes through electronic interactions
描述了磷修饰的氮杂[6]螺旋烯的合成以及这些π共轭双位配体与金属离子的络合。通过第一性原理理论计算对这些金属-双(螺旋)组件的手性光学特性进行了实验评估和研究。结果表明,金属通过与手性 pi 共轭配体的电子相互作用影响这些配合物的手性。
