The synthesis and properties of new metal-free and metallophthalocyanines containing four diloop macrocyclic moieties

Abstract

The synthesis and characterization of new metal-free (9) and metal-containing (Zn, Ni or Cu 10, 11, 12) derivatives of a symmetrically octasubstituted phthalocyanine derived from 21,22-dicyano-2,3,5,6,8,9,11, 12,15,17,18,25,26,28-tetradecahydro[1,4,7,12] benzodioxa-dithiacyclotetradeceno[6,7-b][1,4,7,10,13]benzopentaoxa-cyclopentadecene (7). which was synthesized in a multi-step reaction sequence, have been described. The novel compouds have been characterized by a combination of elemental analysis, H-1 and C-13 NMR, IR, UV-vis and MS spectral data.
