Abstract
A metal-free phthalocyanine ( H 2 Pc ) containing 16-membered N 2 S 2 -donor macrocycles linked to a 2-pyridinyl methyl moiety has been prepared via cyclotetramerization of a phthalonitrile. A metal-free phthalocyanine ( H 2 Pc ) containing four diazadithiamacrocycles a with 2-pyridinyl methyl groups attached was synthesized via cyclotetramerization of 4,5- bis {2-[13(2-pyridinylmethyl)-1,9-dithia-5,13-diazacyclohexadecanyl-5]ethyl} thiophthalonitrile in the presence of DBU as a strong organic base. New compounds were characterized by a combination of elemental analysis, 1 H NMR, 13 C NMR, IR, UV/vis, and MS spectral data.
