Abstract A technique is described for the preparation of novel conjugatively linked tetrathiafulvalenes. The resultant molecule includes two donor moieties which allow the preparation of charge transfer complexes with a band structure higher than the quasi one dimensional structure indigenous to presently known electrically conducting organic complexes.
