Chiral template by chiral metal complex modified electrode

1)。铂电极上的手性模板。我们尝试了在铂电极上进行手性金属络合物修饰的自组装方法。这项工作最早发表在《化学杂志》上。社交界，化学界。本文报道了[*-Os(Bpy)_2LCl]^+(bpy*2，2‘-联吡啶，L*1，2-双(4-吡啶)-乙烷)在铂电极上的自组装，这是首次报道的手性络合物直接键合电极修饰。现在，由于邻菲罗啉(Phen)的配体络合物稳定或不易外消旋而被选为另一种配体化合物，通过合成和光学分离得到了[*-Os(Phen)_2LCl]^+。我们强调，其外消旋络合物修饰的铂电极在乙腈中只有1/4的覆盖率，而在水体系中几乎完全覆盖。碳电极上的手性模板。作为一种新的尝试，我们试图通过金属络合物的直接配体键合来修饰碳电极，这种方法被称为配体接枝法。这种方法将在表面产生手征场方面发挥强大的作用。

1). chiral template on Pt electrode. We have attempted self-assembling method for chiral metal complex modification on platinum electrode. This work was firstly reported in J.Chem. Soc., chem. Commun., 111-112(1997), In this report, [*-Os(bpy)_2LCl]^+(bpy * 2,2'-bipyridyl, L * 1,2-bis(4-pyridyl)-ethane) was reported to be successfully self-assembled on a Pt electrode, which was the first reported as a chiral complex directly bonded electrode modification. Now, as another ligand compound, phenanthroline(phen) was chosen, since its ligand complex is stable or resistant to racemization, and [*-Os(phen)_2LCl]^+ was obtained by synthesis and optical separation procedures. We emphasize that its racemic complex modified Pt electrode showed a solvent-effect that [Os(phen)_2LCl]^+ was self-assembled only 1/4 coverage in acetonitrile, but nearly full coverage in aqueous system.2). chiral template on carbon electrode. As a new attempt, we are trying to modify carbon electrode by direct ligand bonding of metal complex, which method was denoted as ligand grafting method. This method will be powerful in chiral field production on the surface
