Synthesis and spectral parameters of tetra(6-tert-butyl-2,3-quinoxalino)porphyrazine and its metal complexes
摘要:
Tetra(6-tert-butyl-2,3-quinoxalino)porphyrazine and its complexes with bivalent metals were synthesized for the first time by template tetramerization of 6-tert-butylquinoxaline-2,3-dicarbonitrile. The obtained macrocyclic compounds are soluble in hydrophobic solvents. Their electronic absorption spectra in organic solvents and the spectra of the corresponding protonated forms in sulfuric acid were studied.
