Abstract

In this work, we present structural data of the novel, chiral material (-2AH)[PbBr]Br obtained from single crystal X-ray diffraction (SCXRD). This quasi-2D material displays anion-centred clusters within its organic layer, without the need for bi-functional spacers. Instead, the structure is based on the steric properties of the used enantiomerically pure precursors.

摘要

在本研究中,我们展示了通过单晶X射线衍射(SCXRD)获得的新型手性材料(-2AH)[PbBr]Br的结构数据。这种准二维材料在其有机层内呈现以阴离子为中心的簇,无需双功能间隔物。相反,该结构基于所使用的对映体纯前体的空间性质。
