Abstract: 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 H2Pc (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 200˜900 W. This process is noted to reduce drastically reaction time of MPc formation from 8˜24 hours to 10˜30 minutes due to its unique heating by microwave irradiation. Sandwiched type MPc2(such as Lu Pc2) can be produced only through metal replacement from metal-free phthalocyanine by microwave irradiation.
