摘要：

Recently we have studied the interplay between conductivity and magnetism by means of new organic donors containing a stable TEMPO radical. In this work, we have prepared a novel electron donor 1 in which a TEMPO radical part connects to the EDT-TTF skeleton through a pyrrolidine ring. The ESR spectra of 1 indicated three absorption lines (g =2.0062, aN = 15.5 G) characteristic of TEMPO radical, The donor 1 is paramagnetic and showed antiferromagnetic interaction at low temperature region (theta = -2.4 K). The CV measurement revealed 1 shows two pairs of reversible redox waves (+0.48 and +0.86 V vs. Ag/AgCl) and one oxidation wave (+0.83 V).
