Synthesis and characterization of new phthalocyanines containing four 15-membered tetrathiaoxa macrocycles
Özet
A straightforward and generalizable synthesis of metal-free (H-2) and metal derivatives (M = Ni, Co or Zn) of a symmetrically tetrasubstituted phthalocyanine derived from tetrathiooxaphthalonitrile is described. All of these complexes were insoluble in common solvents such as DMF, chloroform, ethanol and water. Structures are suggested based on elemental analyses, IR, NMR (only for intermadiates (I), (II) and (III)), UV-Vis spectroscopy and thermogravimetric analysis.
