Hybrid phthalocyanine derivatives and their uses

(57) -- a summary (1) -- one donor subunit at least which has a desirable excitation peak -- (2) -- it has one acceptor subunit at least which has a desirable luminescence peak -- and a competitive and water-soluble hybrid phthalocyanine derivative useful to un-competitive assay, イムノ assay, and nucleic acid assay is an indication -- and a claim is carried out and the above-mentioned derivative (kind) can perform energy transmission in a molecule from the above-mentioned donor subunit to the above-mentioned acceptor subunit. Such a derivative may contain the electron transfer subunit again. The axial ligand may be carrying out the covalent bond to the metal contained in a water-soluble hybrid phthalocyanine derivative. Ligands, ligand homologs, polypeptides, protein, and nucleic acid can be combined with the axial ligand of dye, and they can form a useful dye complex in イムノ assay and nucleic acid assay.
