以对映体纯氨基酸为结构导向剂，在温和条件下合成了纯手性氯化镉。它们具有缺六方CdCl 2晶格以及一维钙钛矿结构。氯化镉链之间质子化氨基酸和两性离子氨基酸的共存是相当罕见的。这些化合物是非线性光学活性固体，显示出适度的二次谐波产生响应。理论计算揭示了它们的非线性光学性质的起源。
Homochiral cadmium chlorides were prepared under mild conditions using enantiopure amino acids as structure directing agents. They feature a lacunary hexagonal CdCl2 lattice as well as a one-dimensional perovskite structure. The coexistence of protonated and zwitterionic amino acids between cadmium chloride chains is quite rare. These compounds are nonlinear optically active solids showing a moderate second-harmonic-generation response. Theoretical calculations were performed to reveal the origin of their nonlinear-optical properties.
