Abstract
Metal-free and metallophthalocyanine complexes (M = 2H, InCl, or MnCl) containing (2,2-dimethyl-1,3dioxolan-4-yl)methoxy groups were synthesized and characterized. The electrochemical properties of the phthalocyanine complexes were investigated by cyclic and square wave voltammetry. Metal-free and indium phthalocyanines give ring-based oxidation and reduction processes, while manganese phthalocyanine gives both metal and ring-based redox processes. Thin films of phthalocyanines were prepared by spin coating technique. The films were investigated as a function of the different metal ions in the inner core, with the transmittance spectrum measured at a wavelength range of 20 0-10 0 0 nm. The results show that type of metal ions in the phthalocyanine core clearly change the transmittance values of the thin films of phthalocyanine complexes. Surface morphologies of the films were characterized by scanning electron microscopy. It has been observed that metal-free films form a more continuous and non-porous structure, while InPc and MnPc films have a porous surface. (c) 2021 Elsevier B.V. All rights reserved.
