摘要: 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 the aza groups leads to water-soluble products. tetraaza macrocyclic substituents bind transition-metal ions (CoII, NiII, CuII and ZnII) give pentanuclear complexes whose electronic spectra indicate presence monomeric units in solution. thermal stabilities compounds were determined by thermogravimetric analysis.
