Synthesis and Characterization of New Phthalocyanines Containing Thio-Oxa Moieties

Abstract

Metal-free and metal phthalocyanines (M: H<inf>2</inf>, Ni, Co, Zn) 4-7 containing four 9-membered dithiaoxa macrocycles were prepared. The new compounds were characterized by elemental analyses, and IR, 1H-NMR, UV-VIS and DTA. The dithiaoxa-substituted phthalocyanines are less soluble than the aza and oxa-substituted ones.
