Unlocking Singlet Oxygen: Fluorinated Phthalocyanines in Homogeneous and Heterogeneous Photocatalysis

The adsorption and photocatalytic properties of fluorinated phthalocyanines (F64PcZn and F16PcZn [1,2]) on galuminum oxide solid support were investigated. The phthalocyanines along with their metal oxide complexes were characterized by diffuse reflectance, infra red and fluorescence spectroscopies along with thermogravimetric analysis. Phthalocyanines act as photosensitizers using visible light to generate singlet oxygen (1O2) which can react to form other reactive oxygen species (ROS).[3] The
