摘要：

Polymer 1b, [R-N = C <]n, where R is 4-oxyl-3,5-diphenylphenyl, has been synthesized by oxidation of polymer 8 (R = 4-hydroxy-3,5-diphenylphenyl). The latter is prepared by the NiCl2-catalyzed polymerization of the corresponding isocyanide. Magnetic susceptibility measurements indicate no evidence for ferromagnetism or any other short-range ordering among unpaired spins in the temperature region 77-320 K. A spin density of 0.8 spin/repeating unit is measured. ESR spectroscopy indicates that 1b is a paramagnet at both 4 and 320 K.
