摘要：

Ferromagnetic spin coupling of the tert-butylnitroxide diradicals connected to the oligo(1,2-phenylenevinylene)-skeleton was studied to relate with their pi-conjugated electronic structure. The spin coupling constant (J) determined from their magnetic susceptibility increased with the degree of oligomerization in the conjugated skeleton and was reduced in response to the conjugated but spacing phenylenevinylene unit. These 2J values qualitatively agreed with the semiempirically calculated ones.
