Synthesis and Properties of Lanthanide Complexes with Tetrapyrazinoporphyrazine and Its Substituted Derivatives

摘要

Reactions of dicyanopyrazine and its tert-butyl-, diphenyl-, and dipyridyl-substituted derivatives with erbium, thulium, ytterbium, and lutetium chlorides, acetates, and acetylacetonates gave the corresponding tetrapyrazinoporphyrazine metal complexes which were characterized by elemental analyses, and IR, ~1H NMR, and electronic absorption spectra. The stability of the complexes to thermooxidative decomposition in air was also studied.
