Synthesis and structural characterization of peripherally polar substituent zinc phthalocyanine, based on extended π-conjugation concept, were carried out for efficient far- red/near-IR performance in nanocrystalline TiO2 films. The new compounds were characterized using FTIR, UV–Vis, fluorescence spectroscopies, 1H NMR, cyclic voltammetry, differential pulse voltammetry and elemental analysis. From the reduction ...
