Synthesis and spectral luminescent properties of 4,4´,4´´,4´´´-tetra(tert-butyl)-5,5´,5´´,5´´´-tetrakis(phenylsulfanyl)phthalocyanines and their sulfo acids

Magnesium and zinc complexes of 4,4´,4´´,4´´´-tetra(tert-butyl)-5,5´,5´´,5´´´-tetra kis-(phenylsulfanyl)phthalocyanine were synthesized. The corresponding sulfo acids were prepared by sulfochlorination and further hydrolysis. Spectral luminescent properties of the synthesized phthalocyanine derivatives were studied. Introduction of sulfo groups resulted in a bathochromic shift of Q-band in the spectra recorded in DMF and pyridine regardless of the metal nature as well as in a hypsochromic shift in sulfuric acid.
