Newly phthalocyanine derivative which carries 2,6-dimethoxyphenoxy bioactive groups as tetrakis from non-peripheral positions of the phthalocyanine ring and contains strontium (II) as an alkaline earth metal ion in its cavity was synthesized. Its structure was characterized by elemental analysis, fourier transform infrared, ultraviolet–visible, proton nuclear magnetic resonance, carbon-13 nuclear magnetic resonance and matrix assisted laser desorption/ionization time-of-flight mass spectroscopic techniques. Its thermal properties were determined using thermogravimetric analysis and differential scanning calorimetry. The solubility and aggregation behavior in polar protic, polar aprotic and non-polar solvents were determined. Also, its aggregation behavior was studied at a range of different concentrations in dimethyl sulfoxide. The photophysical properties (fluorescence quantum yield, fluorescence lifetime, natural radiation lifetime, non-radiative lifetime, rate constant for fluorescence, non-radiative rate constant and observed fluorescence decay rate constant values) of newly strontium(II) phthalocyanine were determined in dimethyl sulfoxide. In addition, the spectroscopic, thermal and photophysical properties of newly strontium(II) phthalocyanine were also compared with its counterparts reported in the literature. The findings of this work can be useful to those systems involving changes in the forms analogous to the compound studied. In addition, newly strontium(II) phthalocyanine with particularly sufficient and enhanced photophysical properties, could be a photosensitizer candidate for photocatalytic applications.
