Novel CT complexes derived from 4-alkylamino-TEMPO radical and 2,4,6,8-tetr
acyanoazulene have been prepared. Curie-Weiss behavior has been observed in
the magnetic susceptibility of each complex with antiferromagnetic spin-sp
in interactions in the low temperature region on one hand and rather high c
onductivity has been found in the electrical conductivity of each complex w
ith semiconducting behavior on the other hand.
