behaved as a high-spin organic polymer even at room temperature. The trimer model compound, N-(4-5-[N,N-bis(4-methoxyphenyl)amino]-2-methylstyryl}-3-methylphenyl)-N-(4-5-[N,N-bis(4-methoxyphenyl)amino]-2-methylstyryl)phenyl)-4-methoxyaniline, was synthesized from N-(4-methoxyphenyl)-N-(4-vinylphenyl)-3-methyl-4-vinylaniline. The corresponding ammoniumyl triradical displayed an average S (spin quantum
