The synthesis and characterization of new metal-free and metalloporphyrazine containing macrobicyclic moieties

摘要

The synthesis and characterization of new metal-free(8)and metal derivatives of a symmetrically four substituted porphyrazines(7,9)derived from 15,18,23,26-tetraoxa-5,8-dithia-1,12-diazabicyclo[10.8.8]octacos-6-ene-6,7-dicarbonitrile(6),which were synthesized in a multi-step reaction sequence have been investigated.These compounds were prepared starting from dicyanoethylene containing macrobicycle which contains sulfur,oxygen as well as nitrogen heteroatoms.These pigments were characterized by ~1H,~(13)C NMR,IR,UV-vis,mass spectrometry,microanalysis and AA spectrophotometry.
