Özet

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 R-1 at -0.85 V (Delta E-p = 288 mV), one reversible reduction couple R-2 at -1.54 V (Delta E-p = 95 mV) and one quasi-reversible oxidation couple O-1 at 1.07 V (Delta E-p = 135 mV).
