This work presents the synthesis of 4-(2-(ethyl(m-tolyl) amino) ethoxy) phthalonitrile (1) as ligand and its peripherally tetrasubstituted metal-free (2) and metallophthalocyanines (3-5) derivatives. Synthesized compounds were characterized by standart spectroscopy methods. The molecular structure of the ligand (1) was confirmed by single-crystal X-ray diffraction experiment. The crystallographic information file (cif) was uploaded to the data center with CCDC number 1,853,485. The optimized structure of the ligand (1) and the phthalocyanines (2-5) were obtained by using different metods such as B3lyp, HF and m062x method 3-21 g, 6-31 g, sdd basis set. In b3lyp/6-31 + + g(d,p) basis set, H-1 and C-13 NMR chemical shifts, IR spectrum and UV-vis spectrum were measured in gas, chloroform and dimethylsulfoxide phase by means of the obtained optimized structure. Besides, the photophysical and photochemical properties of newly synthesized phthalocyanines (2-5) were investigated in DMSO, comparatively. Singlet oxygen quantum yields of the phthalocyanines (2-5) are ranging from 0.28 to 0.70.
