Abstract
Monoclonal antibodies have been prepared against porphyrins, rhodium phosphine complexes, and binaphthyl derivatives. The monoclonal antibody-porphyrin complex was found to catalyze some redox reactions as enzymes do. In addition, the antibody for porphyrin-acceptor was found to bind porphyrin and when the complex was irradiated by visible light in the presence of viologen and hydrogenase or platinum colloid, hydrogen gas was evolved from aqueous solution. The efficiency is the highest in the protein-porphyirin systems. The monoclonal antibody against rhodium phosphine complex was found to bind the complex and the compound was found to catalyze hydrogenation of amino acid precursors to give almost 100% L-amino acid, although the rhodium phosphine complex is achiral. This is due to the second-sphere coordination effects.
