A calculation based on the one-dimensional tight-binding crystal orbital method shows that the cationic and the dehydrogenated forms of poly(m-aniline) make an organic ferromagnet with high spin multiplicity. On the basis of the calculation, the synthesis and the ESR measurements of the derivatives of this polymer have been performed. We have found from the analysis of g-values that free radicals are created on the N sites of the cationic and the dehydrogenated forms of this polymer. Although the spin concentration is small at present, this polymer attracts our interest as an approach to magnetic polymers.
