Highly conducting complexes were formed (0.5 S/cm for sexiphenyl) but there is no evidence for further polymerization. Paraoligophenylenes have also been reacted with elemental potassium in THF solution with trace amounts of naphthalene. The spectroscopic measurements during AsF 5 doping reveal shifts in absorption bands in the UV and the IR to those characteristic of poly( p‐phenylene). The x‐ray diffraction studies give evidence for a change in lattice spacings to those characteristic of the crystalline polymer. The undoped oligomers and the doped, compensated, and annealed products have been investigated by means of x‐ray diffraction, and UV‐visible and IR transmission spectroscopy. Powders, thin films, and single crystals of p‐phenylene oligomers have been reacted with AsF 5. Conductivities as high as 50 S/cm have been measured. Prolonged exposure to AsF 5 causes a polymerization of these p‐phenylene oligomers to give highly conducting charge‐transfer complexes of poly( p‐phenylene).

These antibodies also introduce a new degree of control over the biological distributions of chelated radionuclides, markedly altering their uptake in tumours and normal organs. These antibodies show a remarkable preference for indium chelates changing to another metal such as scandium or gallium can decrease the antibody-binding constant by more than three orders of magnitude. With the ultimate aim of engineering probe-binding properties into the antibodies themselves, we have now prepared monoclonal antibodies against the EDTA chelate of indium.
Attachment of metal ions to antibodies by means of bifunctional chelating agents can add the diverse nuclear, physical and chemical properties of the metallic elements to these specific binding proteins (ref. Because monoclonal antibodies can recognize and bind to specific groups of atoms such as tumour antigens, they have promise for use in vivo as carriers of radionuclides, drugs or other appended molecules for diagnosis and treatment of disease 1–3.
