Structurally isomeric tetra- and symmetrical octa-substituted metal phthalocyanine dyes were synthesized. Their effects were evaluated according to the number of substituents and the type of metals incorporated in the structures. Ethyl 4-hydroxy-3-methoxybenzoate was attached at the peripheral positions in order to increase the solubility of phthalocyanine. Cu and Zn were chosen as coordination metals, both to increase the thermal stability and to fine-tune the spectral properties. The solubilities of the tetra-substituted dyes[1] were higher than those of octa-substituted in both organic solvents and industrial solvents. Structural analyses of the octa-substituted phthalonitrile’s were achieved using 1H and 13C NMR spectroscopy, and high-resolution mass spectrometry. The structures of the synthesized dyes were confirmed by MALDI-TOF spectroscopy and elemental analysis. Other spectral properties of the dyes were investigated by UV–Vis spectrophotometer, spectrofluorometer, cyclic voltammetry (CV), and thermogravimetric analysis (TGA). |
