讨论了金属表面二维结晶中分子识别的不同立体化学方面。扫描隧道显微镜是一种具有亚分子分辨能力的强大工具，它提供了对分子几何对二维晶格的影响的详细洞察。这里给出的例子包括同向异手性相变、五角形分子平铺、金属表面的手性重构以及不同分子物种的对映体之间通过极性力和van der Waals相互作用进行的非对映异构体识别。
Different stereochemical aspects of molecular recognition in two-dimensional crystallization on metal surfaces are discussed. Scanning tunneling microscopy, a powerful tool with submolecular resolution capabilities, provides detailed insight into the implications of molecular geometry for the two-dimensional crystal lattice. The examples presented here include a homo- to heterochiral phase transition, tiling with pentagonal molecules, chiral restructuring of a metal surface and diastereomeric recognition between enantiomers of different molecular species via polar forces as well as van der Waals interactions.
