A self-assembled supramolecular metallacyclic rectangle was investigated with scanning tunneling microscopy on highly oriented pyrolytic graphite and Au(111) surfaces. The rectangles spontaneously adsorb on both surfaces and self-organize into well ordered adlayers. On highly oriented pyrolytic graphite, the long edge of the rectangle stands on the surface, forming a 2D molecular network. In contrast, the face of the rectangle lays flat on the Au(111) surface, forming linear chains. The structures and intramolecular features obtained through high-resolution scanning tunneling microscopy imaging are discussed.
利用扫描隧道显微镜在高度取向的热解石墨和Au(111)表面上研究了一种自组装超分子金属环矩形。这些矩形在两个表面上均能自发吸附,并自组织形成有序的吸附层。在高度取向的热解石墨上,矩形的长边立在表面上,形成二维分子网络。相比之下,矩形的面则平躺在Au(111)表面上,形成线性链。讨论了通过高分辨率扫描隧道显微镜成像获得的结构和分子内特征。
