Sensor properties for Fe3+ and synthesis of new a bis –(3-(benzhydryloxy) propanoate) phthalocyaninato silicon (IV)

In this study, 3-(benzhydryloxy) propanoic acid (2) and bis –(3-(benzhydryloxy) propanoate) phthalocyaninato silicon (IV) (3) compounds were synthesized. Their compound structures were characterized with the help of IR, UV–visible, mass and ¹H NMR spectroscopy. Aggregation and solubility of the compounds were tested. Finally, the metal sensor property of the axial phthalocyanine compound was investigated against Cu²⁺, Fe³⁺, Mg²⁺, Mn²⁺, Na⁺, Zn²⁺, Ag⁺, Ba²⁺, Cd²⁺ ions. It was determined that the compound was selectively sensitive to Fe³⁺. The optical detection of Fe³⁺ ions in the presence of Cu²⁺, Fe³⁺, Mg²⁺, Mn²⁺, Na⁺, Zn²⁺, Ag⁺, Ba²⁺, Cd²⁺ ions shows that this material can be used for easy and practical analysis.
