Abstract Photosensitized catalysis is the initiation of degradation or transformation reactions of molecules using a combination of light and photoactive materials as catalysts. In this work, 1-benzylpiperidin-4-oxy substituted silicone phthalocyanine (SiPc) 3 has been synthesized and characterized with different spectral data and determined catalytic behavior in p-nitrophenol degradation with 1758 turnover number (TON) and 586 turnover frequency (TOF) values. Metallophthalocyanine 3 is soluble in different organic solvents and investigated aggregation behavior in common organic solvents. Electrochemical properties of metallophthalocyanine 3 was defined by using cyclic voltammetry (CV) technique. Silicone phthalocyanine (SiPc) 3 shows one irreversible reduction couple R1 at −0.85 V (ΔEp = 288 mV), one reversible reduction couple R2 at −1.54 V (ΔEp = 95 mV) and one quasi-reversible oxidation couple O1 at 1.07 V (ΔEp = 135 mV).
