Abstract

This work presents the synthesis and characterization of non-aggregated and highly soluble copper(II) and tin(II) phthalocyanines substituted with 2,6-dimethoxyphenoxy groups at the non-peripheral (alpha) and peripheral (beta) positions. The phthalocyanines have been characterized by common spectroscopic techniques. They show excellent solubility and non-aggregated species in common organic solvents such as dimethylsulfoxide, dimethylformamide, tetrahydrofuran, toluene, acetonitrile, chloroform and dichloromethane, which make them candidates to use for many applications in different fields of science and technology. The effects positions of substituent on the phthalocyanine skeleton and the variety of central metal ions on the phthalocyanine of aggregation and on their spectroscopic properties were determined in different solvents as mentioned above. The novel synthesized copper phthalocyanines were not evaluated for fluorescence, photophysical and photochemical properties due to transition metal and paramagnetic behavior of central metal in the phthalocyanine cavity. The effects of substituent and their positions on the tin(II) phthalocyanines' on their photophysical (fluorescence quantum yields and lifetimes) and photochemical properties (singlet oxygen generation and photodegradation under light irradiation) were also investigated and reported in dimethylsulfoxide for the first time.
