Chiral template by chiral metal complex modified electrode

1). Pt电极上的手性模板。我们尝试了手性金属配合物修饰铂电极的自组装方法。这项工作在J.Chem上首次报道。Soc。,化学。Commun。本文报道了[*-Os(bpy)_2LCl]^+（bpy * 2,2'-联吡啶基，L * 1,2-双（4-吡啶基）-乙烷）在Pt电极上成功自组装，这是首次报道的手性配合物直接键合电极修饰。现在，由于菲罗啉（phen）的配体配合物稳定或不易外消旋，我们选择了它作为另一种配体化合物，通过合成和光学分离得到[*-Os(phen)_2LCl]^+。我们强调其外消旋配合物修饰的Pt电极表现出溶剂效应，[Os(phen)_2LCl]^+在乙腈中仅自组装1/4，而在水溶液中几乎完全覆盖。碳电极上的手性模板。作为一种新的尝试，我们试图通过金属配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。该方法在地面手性油田开采中具有较强的应用价值

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
