New axially aryloxy substituted gallium phthalocyanines for nonlinear optics

Abstract

The ability to control reductions in the saturation energy density is important from the point of view of realizing applications where one would require successive layers in the practical limiter to be fabricated from materials of decreasing saturation energy density. In this paper, two new axially aryloxy substituted gallium phthalocyanine compounds: tBu₄PcGa(p-CPO) and [tBu₄PcGa]₂·SDPO, have been prepared and structurally characterized. Their nonlinear optical (NLO) properties are described.
