摘要
酞毒(Pc ) 的一个 chiral 识别过程的分子水平的鉴定被扫描通道显微镜学(STM ) 在 Cu (100 ) 表面上学习。STM 表明一个 chiral Pc 分子与另外的 Pc 分子形成一系列亚稳的更暗淡的配置。最后， Pc 分子与一样的 chirality 认出另一个 Pc 分子形成一种稳定的更暗淡的配置。Homochiral dimers 在 Cu 表面上被发现，表明 Pc dimerization 的 chiral 特性。为这个 chiral 识别过程的机制被识别，揭示 Cu 表面上的 chiral dimers 的特别吸附几何学的关键角色。
The molecular-level identification of a chiral recognition process of phthalocyanine （Pc） was studied on a Cu（100） surface by scanning tunneling microscopy （STM）. STM revealed that a chiral Pc molecule forms a series of metastable dimer configurations with other Pc molecules. Eventually, the Pc molecule recognizes another Pc molecule with the same chirality to form a stable dimer configuration. Homochiral dimers were found on the Cu surface, demonstrating the chiral specificity of Pc dimerization. The mechanism for this chiral recognition process is identified, disclosing the critical role of the particular adsorption geometry of the chiral dimers on the Cu surface.
