Synthesis, spectroscopy, and photophysical properties of newly magnesium (II) phthalocyanine

Abstract

2(3),9(10),16(17),23(24)-tetrakis-2,6-dimethoxyphenoxy substituted magnesium (II) phthalocyanine, which has very good solubility in polar and non-polar solvents and does not aggregate, was synthesized. Its structure was characterized by spectroscopic methods such as elemental analysis, UV-vis, FT-IR, MALDI-TOF mass and 1 H NMR. It has very good solubility in polar aprotic solvents such as dimethyl sulfoxide, N, N-Dimethylformamide, tetrahydrofuran, dichloromethane, and non-polar solvents such as toluene, chloroform. Its aggregation properties have been studied both in the solvents mentioned above and in N, N-Dimethylformamide at different concentrations. Its photophysical properties were determined in N, N-dimethyl formamide. The effects of the nature and presence of 2,6-dimethoxyphenoxy group, which is an antioxidant derivative, on the phthalocyanine skeleton on the spectroscopic and photophysical properties were investigated by comparing it with unsubstituted magnesium (II) phthalocyanine. It can be a good nominee for various technological applications in that it does not aggregate and has good solubility in polar and non-polar solvents, as well as better and favorable fluorescence properties than its analog in the previous study.

Novel indium(III) acetate phthalocyanine: synthesis and spectroscopic properties

“…Pcs, which are formed by the cyclization of four iminoisoindoline groups over azo bridges, are generally with or without metal depending on the metal substitution in the space on the ring [1,2]. According to the variety of metal bound to Pcs, their properties and usage areas vary [3,4]. By substituting different functional groups on the peripheral or non-peripheral positions of Pc, such as tetra or octa, as well as the presence of different metal species containing ligands in the axial position in its cavity, their aggregation can be prevented by increasing their solubility [5][6][7][8][9].…”
