Polyarylmethyl polyradicals

Preparation and Properties of Monodisperse Aromatic Dendritic Macromolecules [T. X. Neenan, T. M. Miller, E. W. Kwock, H. E. Blair, Chapt. 3, pp. 105-132], High-spin Polyarylmethyl Polyradicals [A. Rajca, Chapt. 4, pp. 133-168]. 

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. 

These values of S are relatively low, compared to those attained in polyarylmethyl polyradicals, especially for the first organic polymer with magnetic ordering and its model compounds (Fig. 2).7,8... 

Polyarylmethyl polyradicals are derived from triphenylmethyl, the first organic free radical discovered by Moses Gomberg in 1900 (Fig. 2).27,28 At that time, the... 

Polyarylmethyl polyradicals were prepared using the carbanion method (Fig. 9), as described in the original communications in 1990 and the other references cited...
