METHOD FOR PREPARING ORGANIC-INORGANIC COMPOSITE MAGNETIC MATERIAL

摘要

The present invention provided a method for manufacturing an organic-inorganic composite magnetic material which has organic radical molecules chemisorbed on the surface of a metal substance and exhibits super-paramagnetism or ferromagnetism. An ionic salt of a metal allowing thiol to be absorbed thereon is reduced with a reducing agent in the presence of a stabilizing ligand so as to form a soluble metal particle. The stabilizing ligand absorbed on the formed soluble metal particle is exchanged with a thiol-substituted organic radical having an unpaired electron so as to synthesize an organic-radical absorbed metal particle.
