Synthesis and characterization of new metal-free and metallophthalocyanines containing macrobicyclic moieties

The synthesis and characterization of novel metal-free and cobalt phthalocyanine, peripherally symmetrically derived from 2,3,6,7,10,11,13,14-octahydro-5H,9H-4,12-(propanothiopropano)-1,8,15,23,4,12-benzote-trathiodiazacycloheptadecane-17,18-dicarbonitrile (4) which was prepared by the reaction of 1,9-diaza-5,13-dithiocyclohexadecane (3) and 1,2-bis(2-iodoethylmercapto)-4,5-dicyanobenzene (2) was carried Out. The novel compounds were characterized by using elemental analysis, H-1, C-13 NMR, IR, UV-vis and MS techniques. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
