Dodeca-phenyl-substituted planar binuclear phthalocyanine magnesium complexes with an extended pi-conjugation system were synthesized with high yields. Two approaches to the extension of the pi-system were presented: extension of an aromatic bridge or a peripheral pi-system. A maximum of near-IR absorption at 972 nm was observed in the case of the planar binuclear naphthalocyanine sharing a common benzene ring. Binuclear phthalo- and naphthalocyanines were characterized by high resolution MALDI-TOF mass spectrometry, UV/Vis/NIR and H-1 NMR spectroscopy. DFT modeling of the structure and chemical shift GIAO calculations were made. The formation of nanoaggregates in a solid film was proven using AFM. The electrochemical properties of binuclear naphthalocyanine complexes were investigated for the first time. (C) 2011 Elsevier Ltd. All rights reserved.

sandwich-type complexes. It was found that intervalence (IV) bands for dinaphthalocyanine complexes were red-shifted about 200 nm in comparison with corresponding diphthalocyanines, reaching 1797 nm for the Eu complex. The electrochemical behaviour of planar and sandwich-type Lu complexes was investigated. For the first time a spectroelectrochemical study of multistep reduction and oxidation processes for
