摘要: 利用电化学扫描隧道显微镜和循环伏安法研究了一种新型的杂杯杂芳烃四氮杂杯芳烃三嗪衍生物在Au(111)表面的自组装结构. 高分辨的STM图像表明, 该杂杯杂芳烃可以在Au(111)表面形成长程有序的单层膜. 此外, 分子以1,3-交替构象吸附, 两个三嗪环平躺在表面, 而苯环倾斜吸附在基底上, 这是分子间与分子-基底间相互作用平衡的结果.

Abstract: Electrochemical scanning tunneling microscopy(EC-STM) and cyclic voltammetry were employed to investigate the self-assembled structure of a new heteroatom-bridged calix(hetero)aromatics, tetraazacalixarenetrizaine derivative on Au(111) surface. High-resolution STM images reveal that the molecules form long-range ordered monolayers. Moreover, the molecule adopts a 1,3-alternate conformation. Two triazine rings lie flatly on Au(111) surface, while two phenyl rings were tilted. This could be attributed to a balance between intermolecular and molecule-substrate interactions.
