摘要：

A couple of naphthalenediimide 4 and 5 and series of perylenediimide derivatives 6-9 carrying TEMPO radical were prepared and their redox, FET, and magnetic properties were investigated. The radical compounds 4 and 6-9 were found to show antiferromagnetic interactions obeying the Curie-Weiss model, while the naphthalenediimide derivative 5 exhibited a singlet-triplet magnetic behavior and it could be well understood by the short oxygen-to-oxygen distance between the spin centers observed in its crystal structure. Owing presumably to their appropriate reduction potentials and structural motifs, exhibitions of n-type FET properties were disclosed in these radical compounds with mobilities of the order from 10(-5) to 10(-8) cm(2) V-1 s(-1) and apparent increase of mobilities was observed in the radical compounds Sand 7 by the surface treatment with HMDS.
