TOWARD A HEXAGONAL GRID POLYMER - INTERACTION OF TENTACLED 1,3,5-TRICARBORANYLBENZENE DERIVATIVES WITH A MERCURY SURFACE

The behavior of nonaqueous solutions of silyl]-1,12-dicarba-closo-dode caboran-1-yl]benzene (2) and four simpler related compounds on a mercu ry electrode was studied by cyclic voltammetry and ac impedance measur ements. It was established that 2 is attached to mercury in two differ ent ways depending on the applied potential, while the interaction of the other compounds with the electrode is less pronounced. At relative ly negative potentials 2 is weakly adsorbed at the electrode. At posit ive potentials a strongly adsorbing mercury ion complex of 2 is produc ed and forms a compact surface layer. The influence of the supporting electrolyte and the solvent has been examined.
