New phthalocyanines (M = Cu, Zn, Ni, Co or 2H) substituted with four 17-membered trioxadiaza macrocycles have been prepared. Detosylation of aza groups with concentrated sulfuric acid simultaneously leads to sulfonated groups on the aromatic rings of the macrocyclic substituents. While the N-tosylated derivatives are soluble in organic solvents, the detosylated ones are extremely soluble in water.The electrical conductivities of the phthalocyanines measured as gold sandwiches are about 1 0-l2 S m-' in vacuo and show some increase in the presence of dry air.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
