Several titanium phthalocyanines tetra- and octa-substituted with dimethylaminoethylsulfanyl groups on peripheral positions have been synthesized and characterized. These phthalocyanines were converted into water-soluble quaternized products by reaction with methyl iodide. The capping of the titanyl (metaloxo) inner core with catechol and 2,3-dihydroxynaphthalene and complexation of peripheral donor groups of octakis(2-dimethylaminoethylsulfanyl)phthalocyaninatooxotitanium (IV) with Pd(II) ions to obtain multinuclear product were also studied. The new compounds were characterized using elemental analyses, H-1 NMR, IR, mass and UV-vis spectral data. (C) 2006 Elsevier Ltd. All rights reserved.
