摘要:This invention provides a novel process for preparing soluble phthalocyanines by microwave irradiation in the absence of any organic solvent. Three different starting materials, i.e. t-butylphthalic anhydride, t-butyl phthalonitrile and metal-free H 2 Pc (tetra-t-butylphthalocyanine) have been adopted, respectively. The starting material with proper metal compound, such as chloride or acetate were irradiated in a commercial microwave oven for a period of 1 to 30 minutes at a power of 200Ëœ900 W. This process is noted to reduce drastically reaction time of MPc formation from 8Ëœ24 hours to 10Ëœ30 minutes due to its unique heating by microwave irradiation. Sandwiched type MPc 2 (such as Lu Pc 2 ) can be produced only through metal replacement from metal-free phthalocyanine by microwave irradiation.
