We systematically examined the effects of π-electron systems on the chiroptical activity of atomically precise gold clusters [Au11(DP)4L2]+, where DP and L represent chiral diphosphines and achiral anionic ligands, respectively. Reducing the distance between the π-electron systems of the chiral DP and the Au11 core enhanced the anisotropy factor of [Au11(DP)4L2]+ in the range of 300–450 nm while extension of the π-electron system of the achiral L did not. This tendency supports our previous proposal that the proximity of the chiral π-electron system to the gold core amplifies the optical activity.

π-电子系统对手性二膦保护的Au11团簇光学活性的影响

我们系统地研究了 π 电子系统对原子级精确金簇 [Au 11 (DP) 4 L 2 ] + 的手性光学活性的影响,其中 DP 和 L 分别代表手性二膦和非手性阴离子配体。减小手性DP的π电子系统与Au 11核之间的距离,增强了[Au 11 (DP) 4 L 2 ] +在300-450 nm范围内的各向异性因子,同时扩展了π电子系统非手性 L 没有。这种趋势支持我们之前的提议,即手性 π 电子系统与金核的接近会放大光学活性。
