We developed a new strategy, ligand exchange strategy, for tuning the response speeds of helicity inversion of a metal-containing helical structure. This is based on the exchange of the two axial amine ligands of the octahedral Co centers in the metallocryptands [LCo X ] (X=axial amine ligand). The response speeds of the helicity induction were controlled by using different combinations of achiral and chiral amines as the starting and entering ligands, respectively. The response speeds of the helicity inversion from P to M were also tuned by using different combinations of chiral amines.
我们开发了一种新策略，配体交换策略，用于调节含金属螺旋结构的螺旋翻转响应速度。这是基于八面体 Co 中心的两个轴向胺配体在金属穴醚[LCoX]（X=轴向胺配体）中的交换。手性和非手性胺分别作为起始和进入配体的不同组合来控制手性诱导的响应速度。通过使用不同组合的手性胺，也可以调节从 P 到 M 的螺旋翻转的响应速度。
