Two-dimensional (2D) nucleation and crystallization of the helical aromatic hydrocarbon heptahelicene on the single crystalline copper(100) surface has been studied with scanning tunnelling microscopy. In contrast to previously observed racemic 2D crystals on Cu(111), separation into homochiral domains is observed for Cu(100).
利用扫描隧道显微镜研究了螺旋芳烃七并苯在单晶铜（100）表面的二维（2D）成核和结晶过程。与之前在铜（111）上观察到的外消旋二维晶体不同，在铜（100）上观察到了分离成纯手性畴的现象。
