Spectroelectrochemical characterisation of a poly[Ni(saltMe)] modified electrode
Vilas-Boas, Miguel; Freire, C.; Castro, B.; Christensen, P.A.; Hillman, A.R.Electrogenerated polymers based on the nickel(II) compIex 2,3-dimetbyl- N,N -bis(salicylidene )butane-2,3- diaminatoniekel(II), poly[Ni(saltMe)], were characterized by in situ FTIR and UV/Vis spectroscopy and ex-situ EPR spectroscopy in order to gain insights into film structure, electronic states and charge conduction. The role of the nickel ions during film oxidation was probed by using EPR to study naturally...

Vilas-Boas, Miguel; Freire, C.; Castro, B.; Christensen, P.A.; Hillman, A.R.Oxidative electrochemical polymerization of (N,N'-ethylenebis(salicylideneaminato)) nickel(II), [Ni(salen)], in acetonitrile/TEAP was reinvestigated. The polymers were characterized by in situ FTIR and UV-visible spectroscopies in order to explore film structure and to clarify the electronic states as a function of the electrochemically controlled applied redox potential; oxidized species involved in polymeriza...
