The preparation and characterization of some π-donors with a pyrazine-edge-group as well as with tetrathiapentalene-, thiophene-, and dihydrobenzoselenophene-spacer-groups are de scribed. Some of these donors give conducting charge transfer complexes with TCNQ and/or cation radical salts with I3 -, BF4 -and PF6 -as counter anions.
