Abstract
Several biradicals consisting of 4-substituted-amino-TEMPO were prepared fr om 4-oxo-TEMPO with certain diamines as piperazine, ethylenediamine, 1,2-tr ans- or cis-cyclohexanediamine by reductive amination reaction. A series of CT complexes derived from the biradicals and accepters was then prepared a nd their magnetic behavior was investigated comparing with the original bir adicals. Although the ferromagnetic behavior was observed in the biradical derived piperazine, antiferromagnetic behavior was predominantly observed i n other biradicals or CT complexes derived therefrom.
