手性表面上的对映选择性化学是结构敏感表面化学的典型形式，纯粹源于表面结构的不对称性。由于手性分子与手性表面的对映体特异性相互作用能量的大小有限，因此识别或设计能够最大限度地提高给定过程对映体选择性的手性表面结构极具挑战性。使用球形铜单晶暴露表面与连续的2D分布的晶体取向，我们已经映射的对映体特异性表面反应动力学的酒石酸分解在整个表面取向空间。这些测量揭示了对映体选择性的机械起源，并确定了最对映体表面取向的结构特征。
Enantioselective chemistry on intrinsically chiral surfaces is the quintessential form of structure sensitive surface chemistry, arising purely from the dissymmetry of the surface structure. Identification or design of chiral surface structures that maximize enantioselectivity for a given processes is extremely challenging because of the limited magnitude of the enantiospecific interaction energetics of chiral molecules with chiral surfaces. Using spherically shaped Cu single crystals exposing surfaces with a continuous 2D distribution of crystallographic orientations, we have mapped the enantiospecific surface reaction kinetics of tartaric acid decomposition across surface orientation space. These measurements reveal both the mechanistic origin of enantioselectivity and identify the structural features of the most enantiospecific surface orientation.
