New metal-free 3 and metallophthalocyanines 4-5 (M = Ni or Zn) substituted with four 20-membered tetraaza-dioxa macrocycles from 21,22-dicyano-2,8,11,17-tetra-(toluene-p-sulfonyl)-1,2,3,4,5,6,7,8,9,10,11, 12,13,14,15,16,17,18-octadecahydrox[l] [2,8,11,17]tetraaza [4,13]dioxadicontine (2) are described. Cyclotetramerization of the substituted phthalonitrile (2) leads to a product very soluble in common organic solvents. The characterization of the compounds was accomplished by elemental analysis, H-1,C-13 NMR, IR, UV-vis and MS spectral data. Copyright (C) 1996 Published by Elsevier Science Ltd
