用扫描隧道显微镜研究了一种前手性喹吖啶酮衍生物（QA 16 C）在Cu（110）表面的吸附行为。QA16C分子更喜欢在150 K组装成短的纯手性分子线，具有两个对映体取向，其中侧链烷基链表现出部分无序。随着S样品温度的升高，QA16 C线形成更大的有序的纯手性域。作为同手性识别的一个原因，我们确定了由于与substraw的相互作用的分子的刚性对齐。此外，横向分子间相互作用的氢键和货车范德华相互作用的形式被确定。
The adsorption of a prochiral quinacridone derivative (QA16C) with two alkyl chains of 16 carbon atoms on a Cu(110) surface wits investigated with scanning tunneling microscopy. QA16C molecules prefer to assemble at 150 K into short homochiral molecular lines with two enantiomorphous orientations in which the lateral alkyl chains exhibit partial disorder. With increasing S sample temperatures, the QA16C lines form larger well-ordered homochiral domains. As a reason for the homochiral recognition, we identify a rigid alignment of the molecule due to the interaction with the substraw. In addition, lateral intermolecular interactions in the form of hydrogen bonding and van der Waals interactions are identified.
