The first synthesis and characterization of new metal-free and metallophthalocyanine containing 33-membered crown ether moieties

Abstract

The synthesis and characterization of novel metal-free and metallophthalocyanines, fused symmetrically in non-peripheral positions with four octaoxamacrocycle has been synthesized by cyclotetramerization of the 2,5,8,11,14,20,23,26,29,32-decaoxatricyclo [31.2.2.115,19] octatriconta-1(36),15,17,19(38),33(37),34-hexaene-34,35-dicarbonitrile (5) which was prepared by the reaction of 3,6-bis[2-(2-{2-[2-(toluene-4-sulphonyl)- ethoxy]-ethoxy}-ethoxy)-ethoxy]-phthalonitrile (3) and 1,3-dihydroxybenzene (4). The novel compounds were characterized by using elemental analysis, 1H, 13C NMR, IR, UV-vis and MS spectral data. © 2013 World Scientific Publishing Company.
