Although phthalocyanines were first used only as pigments and dyestuffs, they have
been used as advanced technology materials in chemical sensors, liquid crystal,
non-linear optics and photodynamic therapy applications in the last 20 years. The
addition of different groups to the phthalocyanine core provides the production of
new materials with the necessary functions for different application areas [1]. In this
study, silicon phthalocyanine compounds in which two different groups are
substituted to the phthalocyanine ring in axial positions were synthesized and
characterized. Then, silicon phthalocyanines and modified TiO2 nanoparticles were
synthesized by sol-gel process under reflux [2]. By determining the crystal
structures of the obtained modified TiO2 nanoparticles, zeta potential and particle
size distribution measurements were carried out. In the determination of the
photocatalytic activities of the prepared coatings, the degradation of methylene blue
as a model impurity was investigated comparatively.
