Synthesis and characterization of new phthalocyanines containing thio-oxa-ether moieties

Abstract

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