Electro-click coupling : a bottom-up strategy for functionalizing surfaces and assembling functionnal coatings

Gaulthier Rydzek National Institute for Materials Science, Tsukuba, Japan

Nanoarchitectonics materials recently opened promising perspectives for a broad range of applications including energy conversion, catalysis, optical, and electronic devices.[1] However, integration of functionnal building blocks on surfaces still suffers from a lack of versatility and specificity. This talk highlights the potential of electro-click as a film deposition method that can overcome these challenges. Simple and selective growth of both polymeric and inorganic/hybrid structures was achieved on surfaces from a one-pot solution by using an electrochemical stimulus.[2-5] Building blocks bearing either alkyne or azide chemical functions were covalently coupled on electrodes by local electrogeneration of a Cu(I) catalyst.[6] Recent progresses aiming at gaining a better control on the film nanostructure as well as coupling with electropolymerization methods will be addressed.[7,8]
