通过扫描隧道显微镜(STM)观察到外消旋半胱氨酸部分热脱附/分解后,在Au(110)-(1×2)表面上出现了明显的对映体过量。我们系统地研究了几个可能的起源,这个有趣的观察手征对称性破缺,包括手性偏置的基板,但仍然无法确定来源。
A pronounced enantiomeric excess of ll-cysteine dimers is observed by scanning tunneling microscopy (STM) on the Au(110)-(1×2) surface after partial thermal desorption/decomposition of racemic cysteine. We systematically examine several possible origins for this intriguing observation of chiral symmetry breaking, including a chiral bias of the substrate, but remain unable to identify the source.
