A gallium phthalocyanine dimer with a direct gallium - gallium bond, [tBu(4)PcGa](2) . 2dioxane (2), has been synthesized and characterized by Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy, UV/Vis, IR, NMR and MALDI-MS. By EXAFS the gallium - gallium distance in 2 was found to be 2.46 Angstrom. Dimer 2 exhibits reverse saturable absorption with significantly reduced saturation intensity with respect to the starting material tBu(4)PcGaCl ( 1) as determined by means of optical limiting experiments.

Abstract

A gallium phthalocyanine dimer with a direct gallium - gallium bond, [tBu(4)PcGa](2) . 2dioxane (2), has been synthesized and characterized by Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy, UV/Vis, IR, NMR and MALDI-MS. By EXAFS the gallium - gallium distance in 2 was found to be 2.46 Angstrom. Dimer 2 exhibits reverse saturable absorption with significantly reduced saturation intensity with respect to the starting material tBu(4)PcGaCl ( 1) as determined by means of optical limiting experiments.
