“…According to the results obtained, the highest yield of singlet oxygen was observed in DMSO which is an important solvent because it is compatible with body fluid and is not toxic at the concentration studied 50 . The physical properties of solvents, including dielectric constant, thermal conductivity, Grunesian coefficients (which indicate the photoacoustic efficiency of the absorber) and vapor pressure, can impact the photophysicochemical and sonophotochemical properties of sensitizers 51–54 . There are two types of interactions between the solvent and organic solute: specific and nonspecific.…”

[51][52][53][54] There are two types of interactions between the solvent and organic solute: specific and nonspecific. These interactions can cause changes in the electronic structure and dipolar moment of the sensitizer molecules.…”

To treat a life‐threatening disease like cancer, photodynamic therapy (PDT) and sonodynamic therapy (SDT) methods were combined into sono‐photodynamic therapy (SPDT) as an effective therapeutic solution. Each day, the usage of phthalocyanine sensitizers increases in the therapeutic applications as they have the ability to produce more reactive oxygen species. In this context, a new diaxially silicon phthalocyanine sensitizer, containing triazole and tert‐butyl groups, was synthesized. After elucidating the structure of the complex with elemental analysis, FT‐IR, UV–Vis, MALDI–TOF MS and 1H NMR, its photophysical, photochemical and sono‐photochemical properties were examined. When singlet oxygen generation capacity of the new synthesized silicon phthalocyanine complex was determined and compared among photochemical (PDT; ФΔ = 0.59 in DMSO, 0.44 in THF, 0.47 in toluene) and sonophotochemical (SPDT; ФΔ = 0.88 in dimethyl sulfoxide (DMSO), 0.60 in tetrahydrofuran (THF), 0.65 in toluene) methods, it can be said that the complex is a successful sono‐photosensitizer that can be used as a good SPDT agent in vitro or in vivo future studies.
