New polycyclic organic radicals e.g. useful in biochemistry, magnetic materials, electrically conductive materials, superconductors, analysis, oligomers and polymers

摘要

Polycyclic organic radicals (I) are new. Polycyclic organic radicals (I) of formula (Ia)-(Ic) are new. X = N, As or P; Y = O, S, Se or NR; R = optionally substituted alkyl or aryl; R1-R16 = H, optionally substituted alkyl, cycloalkyl, aryl or heteroaryl, or N-, O-, S- or P-containing groups, and A, B, C', D = carbocyclyl or heterocyclyl.
