Abstract
A water-stable homochiral luminescent metal-organic framework (HLMOF), {[Cd(l)(4,4'-bipy)]·DMA·5H2O}n (1), was obtained by a spontaneous symmetry-breaking crystallization from achiral precursors without any enantiopure auxiliary. The homochirality of 1 was confirmed by single-crystal X-ray diffraction and CD spectroscopy. Complex 1 exhibits an interesting enantioselective sensing of d/l-penicillamine in water.
摘要
一种水稳定的手性发光金属有机骨架（HLMOF），[{Cd(l)(4,4'-bipy)]·DMA·5H2O}n（1），是由非手性前体制备，无需任何对映体纯助剂，通过自发对称破缺结晶得到的。1 的手性通过单晶 X 射线衍射和 CD 光谱得到证实。配合物 1 在水中对 d/l-青霉素胺具有有趣的手性选择性传感。
