4-Azidoaniline-based electropolymer as a building block for functionalisation of conductive surfaces

We propose in this work to compare three approaches using 4-azidoaniline combined with “click” chemistry and electrochemistry to anchor ferrocene moieties at glassy carbon surfaces. The immobilisation of a newly synthesised molecule, 4-(4-ferrocenyl-1H-1,2,3-triazol-1-yl)aniline, through direct electropolymerisation or via in situ diazotization followed by electrografting is studied by analysing the samples by XPS and electrochemistry.

► 4-Azidoaniline used for synthesis of electrodeposable molecules by click chemistry. ► Study of electropolymerisation and electrografting of the new molecules. ► Presence of immobilised ferrocene evidenced by XPS and cyclic voltammetry studies.
