Octasolketal-substituted phthalocyanines: synthesis and systematic study of metal effect and substitution pattern on 13C NMR

Abstract

A complete series of solketal octasubstituted phthalocyanines have been synthesized, with peripheral (beta) or non-peripheral (alpha) substitution pattern. Their C-13 NMR and UV-vis properties are compared relatively to this substitution pattern or the nature of the central metal (Ni, Zn or H-2).
