摘要
在Cu{110}表面上研究了R-和s -苯基甘氨酸以及两种对映体的定量明确的混合物。在饱和覆盖下，分子形成有序的手性结构，具有手性单位细胞，确保两个对映体的LEED模式易于区分。并与Cu{110}吸附的非手性物质甘氨酸和R-， s -丙氨酸的类似结构进行了比较。
The formation of enantiospecific phases on a Cu{110} surface
Both R- and S-phenylglycine and a quantitatively well defined mixture of the two enantiomers have been studied on Cu{110} surfaces. At saturation coverage, the molecules form well ordered, chiral structures with a chiral unit cell which ensures that the LEED patterns of the two enantiomers are readily differentiated. Comparison is made with analogous structures observed for the non-chiral species glycine and R-, S-alanine adsorbed on Cu{110}.
