Synthesis and Spectral Properties of New Octamethyl Substituted Tetrapyrazinoporphyrazines

Abstract

Efficient synthetic approach to a new magnesium and zinc complexes of methyl substituted tetrapyrazinoporphyrazine was developed. The optimization of reaction conditions for preparation of initial pyrazine-2,3-dicarbonitrile was carried out, using cerium ammonium nitrate as a catalyst. The target complexes were characterized by MALDI-TOF mass spectrometry and NMR spectroscopy. Spectral properties were investigated using UV-Vis and fluorescence spectroscopy.Keywords: Porphyrazine, UV-Vis spectroscopy, fluorescence, microwave irradiation, pyrazine-2,3-dicarbonitrile.

Photoactive layers for photovoltaics based on near-infrared absorbing aryl-substituted naphthalocyanine complexes: preparation and investigation of properties

“…As it is usually observed for lanthanide (III), Zn and Mg monophthalocyanines the nature of the central ion does not influence the Q band position. 35,[37][38][39] Strong intermolecular interactions in a film results in broadening of the Q band and a ca 30 nm bathochromic shift of its maximum (Fig. 2).…”
