This study includes the synthesis of two novel 4,5-bis((4-methoxyphenyl)thio)- and 4-chloro-5-((2,4,6-trimethoxyphenyl)thio)-substituted phthalonitrile compounds (1 and 2, respectively) and their corresponding metal-free (3 and 4) and manganese (5 and 6) derivatives. The molecular structures of the phthalonitrile (starting) compounds were characterized using classical methods, including elemental analysis, FT-IR, 1H and 13C NMR spectra. Their phthalocyanine (Pc) derivatives were characterized by elemental analysis, FT-IR, UV–Vis, and MALDI-TOF-MS. Electrochemical and in situ spectroelectrochemical analyses of the compounds were also performed using electroanalytical techniques, including cyclic voltammetry, square wave voltammetry, and in situ spectroelectrochemical methods in the DMSO/TBAP electrolyte medium to describe the redox properties of the phthalocyanines (Pcs) (3–6). Metal-free H2Pc (3 and 4) compounds displayed ring-based redox behaviors. On the other hand, the Mn(OAc)Pc (5 and 6) complexes exhibited rich redox behavior, accompanied by additional metal-based electron transfer processes. These processes gave distinct spectral and color changes, which make them usable as electrochromic materials in applicable technologies.
