Spectral properties and solubility of the lanthanide complexes with substituted and annelated porphyrazines

An analysis of the electronic optical properties and solubility in chloroform and DMF of the erbium and ytterbium complexes with porphyrazine and its octaphenyl- and octa(p-alkylsulfamoylphenyl)-substituted derivatives and tetrapyrazinoporphyrazine and its octaethyl-, tetra(tert-butyl)-, and octaphenyl-substituted derivatives is presented. The dependence of the electronic optical properties and solubility on the composition of the macrocycle of the studied complexes, namely, on the nature of the extraligand and peripheral environment of the porphyrazine macrocycle, is shown.
