Abstract

Tetra-substituted palladium phthalocyanine complexes with different electron withdrawing and electron donating substituents (–H,–NO2,–NH2,–Cl,–COOH, aryl thio) have been synthesized with a good yield. The synthesized complexes were characterized using XPS, UV–Vis, IR, Raman, XRD, TGA and electrochemistry. The XPS spectra show that the central metal ion is in the+ 2 state, while the UV–Vis spectra demonstrate split absorption peaks ...
