PROCEDURE
实验过程
2 g (3.24 mmol) of dihydroxygermanium-phthalocyanine are boiled at reflux with 2 equivalents of diphenylhexadecyloxysilanol in 210 ml of dioxane for 39 hours. After 24 hours, 500 mg of dihydroxygermanium-phthalocyanine are added. The reaction mixture is allowed to cool and the residue is chromatographed on basic aluminium oxide (Alox B) using pure hexane and hexane/ethyl acetate (4:1) in succession as eluants. The product-containing fractions are combined and concentrated. The residue is recrystallised from pentane at -20° C., yielding blue crystals of bis(diphenylhexadecyloxy-siloxy)germanium-phthalocyanine.
