The synthesis, liquid crystalline, photophysical and photochemical properties of the peripheral- and non-peripheral-tetra-substituted alkylthio gallium(III) phthalocyanines are reported here for the first time. These novel compounds have been characterized by elemental analysis, UV–Vis, IR and 1 H NMR spectroscopy and mass spectrometry. The thermal stabilities of the phthalocyanine compounds...
The photoprocesses of meso-tetra(4-sulfonatophenyl)porphyrin and meso-tetra(4-hydroxyphenyl)porphyrin were studied in the presence of lysozyme. Light-induced damage of the dyes and proteins were measured in aqueous solution at pH 4 and 8 under the exclusion of oxygen. The results were compared with those of bovine serum albumin, where virtually no photooxidation takes place. Non-covalent binding to...
