mixed donor macrocyclic moieties

The new phthalocyanine peripherally substituted with a twelve-membered dioxadiaza macrocycle was synthesized by cyclotetramerization of 1,2-bis(2-{4'-[(4'-methylphenyl)sulphonyl]- 1',7'-dioxa-4',10'-diazacyclododecane})-4,5-dicyanobenzene (4) which was obtained from 1,2-bis(2-{4'-[(4'-methylphenyl) sulphonyl]-1',7'-dioxa-4',10'-diazacyclododecane})- 4,5-dibromobenzene ( 3). Metallophthalocyanine was also prepared by the reaction of the dicyano-substituted macrocycle in the presence of anhydrous CuCN. The new compounds were characterized by a combination of elemental analysis, H-1 and C-13 NMR, IR, electronic and mass spectroscopies.C1 Karadeniz Tech Univ, Dept Chem, TR-61080 Trabzon, Turkey.Pamukkale Univ, Dept Chem, TR-20100 Kinikli Denizli, Turkey
