Publication date: Available online 12 April 2019Source: Journal of Molecular StructureAuthor(s): Ümit Demirbaş, Duygu Akyüz, Hakkı Türker Akçay, Atıf Koca, Halit KantekinAbstractThe 1,4-benzodioxane substituted phthalonitrile compound (3) and non-peripherally tetra substituted cobalt(II) (4), nickel(II) (5) and copper(II) (6) phthalocyanine complexes were synthesized. The structural characterization of the compounds was performed by using various spectroscopic techniques. The electron transfer properties of the phthalocyanine complexes (4–6) were investigated by voltammetric and in situ spectroelectrochemical measurements. The electrochemical and spectroelectrochemical properties of the non-peripherally tetra substituted metallo-phthalocyanines (4–6) having redox active and inactive metal center were compared with each other in terms of electrochemical responses and the differences were revealed.Graphical abstract
