The synthesis and characterization of new metal-free and metallo porphyrazines bearing peripheral aza-18-crown-6 moieties

摘要

Metal-free and metalloporphyrazines bearing substituted aza-18-crown-6 moieties in peripheral positions were prepared and characterized by elemental analysis,IR,~1H and ~(13)C NMR,UV-vis and MS spectral data.Phthalocyanines and porphyrins have received considerable attention due to the number of applications in which these two families of compounds have been employed and also because of their interesting properties[1].
