Abstract
The notoriously non-selective aryl-diazonium surface-functionnalization turned selective in the presence of the electron-deficient heterocycle. The electro-activation of the probe allowed the rapid and nearly quantitative liberation of covalently tethered ligands.

A conceptually novel coating strategy is presented based on the selective oligomerisation of picoliniumderived end-tethered polymer chains
The construction of ‘‘smart‘‘ interfaces on glassy carbon and gold electrodes was presented in which the electron deficient redox probe offers the fragmenting ability and plays key roles in the construction of surface-capped oligomers
Summary
Paper mediated functionalization was advantageously used for the coating of electrode surfaces as well by applying a slight negative electrode potential (Ered = – 0.50 V vs Ag/AgCl) to induce the reduction of the corresponding diazonium salt,[16,17,27] triggering a reaction with the surface.[16,18]
