摘要：

The self-assembly of monodispersed supramolecular nanoclusters was observed by scanning tunneling microscopy (STM). The clusters form from the naturally occurring amino acid cysteine by vapor deposition onto the Au(110)-(1 × 2) surface under ultrahigh vacuum conditions. Enantiomerically pure l- and d-cysteine yields clusters with mirror-image STM signatures. Racemic LD-cysteine segregates into homochiral clusters, evidencing specific intermolecular interactions during the self-assembly process. Copyright © 2003 American Chemical Society.
