This review outlines the design and characterization of very high-spin polyradicals. The rational, bottom-up design and characterization of polyarylmethyl polyradicals with increasing number of exchange coupled unpaired electron spins are described. [Pg.168]

A very high-spin polyradical may be defined as a molecule or polymer in which the electronic ground state possesses very large value of total spin quantum number S (high-spin ground state). Since the values of S are related to the net number of ferromagnetically coupled unpaired electrons (parallel spins), such molecules and... [Pg.168]
