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.

Dodecaphenyl-substituted planar binuclear naphthalocyanine magnesium complex possessing an intense absorption in the near IR region up to 1100 nm has been synthesized on the basis of novel 2,3-dicyano-6,7-diphenylnaphthalene.
