The two-dimensional ordering of a number of 2,2'-bipyridine derivatives at the liquid/solid interface has been investigated by scanning tunneling microscopy. By appropriate functionalization of the bipyridine units, their intermolecular distance can be tuned, which has proved to be crucial for complexation with metal ions. The in situ addition of metal salts (Pd(2+), Cu(2+)), leading to the formation of metal-bipyridine complexes, has a dramatic influence on the two-dimensional ordering of the molecules and suggests that these complexes could be used as templates.
通过扫描隧道显微镜研究了多种2,2'-联吡啶衍生物在液/固界面的二维排列。通过对联吡啶单元进行适当的功能化,可以调节它们的分子间距离,这已被证明对于与金属离子的络合至关重要。原位添加金属盐(Pd(2+)、Cu(2+))导致形成金属-联吡啶络合物,对分子的二维排列有显著影响,并表明这些络合物可用作模板。
