Özet

The synthesis of a new copper(II) phthalocyaninate substituted with four 15-membered tetraazamacrocycles from 15,16-dibromo-2,5,9,12-tetra(toluene-p-sulphonyl)-2,3,4,5,6,7,8,9,10,11,12,13-dodecahydro-1H-2,5,9,12-benzotetraazacyclopentadecine is described. Quaternization of the aza groups leads to water-soluble products. The tetraaza macrocyclic substituents bind transition-metal ions (Co(II), Ni(II), Cu(II) and Zn(II)) to give pentanuclear complexes whose electronic spectra indicate the presence of monomeric units in solution. The thermal stabilities of the compounds were determined by thermogravimetric analysis.
