N2 - Ultrathin films containing water-soluble copper (II) phthalocyanine-3,4′,4″,4‴- tetrasulfonic acid (CuPcTs) and poly(diallyldimethylammonium chloride) (PDADMAC) were fabricated using the electrostatic layer-by-layer deposition technique. UV-vis absorption spectra and ellipsometry measurements suggested successive linear depositions of the bilayers of CuPcTs and PDADMAC. The thickness of the CuPcTs monolayer obtained from the ellipsometry was smaller than the plain size of CuPcTs and the molecule planes were considered and tilted in the film. The surface morphology was also observed using atomic force microscopy. The cyclic votammogram (C-V) of the fabricated films in 0.1 M KCl aqueous solution suggested the oxidation and reduction of the CuPcTs at approximately +0.9 and +0.05 V vs. Ag/AgCl, respectively. UV-vis absorption spectra were observed for the films at applied voltages of +0.9 and 0.0 V in the KCl aqueous solution and electrochromisms were repeatedly observed.
