AFFINITY OF THE POLY-DB18-C6 RESINS TOWARDS NI2+ CATIONS AND VARIOUS ORGANIC SUBSTRATES

The modification of electrode surfaces by nickel, to promote catalytic hydrogenation, is of interest to electrochemists. The first part of t his article deals with attempts to increase the amount of Ni2+ cations in the poly-DB18-C6 matrix. The amount of Ni2+ can be increased by pr eviously inserting in the polymeric matrix a chemical known to form st able complexes with this cation. In the second part are presented firs t results of the insertion in poly-DB18-C6 of various chemicals presen ting potential chemical, electrochemical or even biological interest i n view of their use as electrode modifiers (to accelerate charge trans fer) or even biosensors.
