Condensation reactions between (4-amino-2, 6-dichlorophenyl) bis (2, 4, 6-trichlorophenyl) methyl radical and a new hexafunctionalized radical of the TTM series, tris (3, 5- dichloroformil-2, 4, 6-trichlorophenyl) methyl radical or its corresponding diamagnetic precursor 6 yield macromolecular heptaradical 3 and hexaradical 4, respectively, with high magnetic purity. Both solid polyradicals show stability in nitrogen at temperatures up to ...
