摘要：

Polyradicals are polymers with saturated or conjugated backbones containing a succession of paramagnetic centres. Synthetic strategies and methods of characterization are described with examples of each. Unconjugated polyradicals, e.g. poly(TEMPOacrylate), are useful catalysts for the oxidation of amines and alcohols. Conjugated polyradicals include polypyrroles and polythiophenes functionalized with nitroxide, quinone, and viologen units. Polyradical-coated electrodes catalyse redox reactions of organic substrates. Spin cooperation may be induced by certain structural features. Developments in the search for organic ferromagnets are surveyed. Possibilities for superconductivity in polyradicals are briefly treated.
