As model compounds to petroleum fractions, the novel phthalocyanine derivative was synthesized and characterized. The self-association behavior of the phthalocyanine derivatives in water-DMSO were investigated by UV-visible (UV-vis) absorption spectra.

The UV-Visible absorption spectroscopy was performed to study the SrTiO3 (STO) single crystals implanted with the fluences of 1.5×1015 and 1.875×1016 Ar+/cm2. The two absorption peaks at 425 and 742 nm were recorded for the low-fluence implanted samples, while the additional peak at 520 nm was measured only for the high-fluence implanted samples. Through the evolution of the absorption peak with the annealing temperature, the 425, 520, and 742 nm peaks are attributed to the isolated oxygen vacancies, oxygen bivacancies, and oxygen interstitials, respectively. The thermal evolution of absorption spectra reveals that the STO lattice defects have poor thermal stability and disappear completely after 400°C annealing treatment.
