The donor-acceptor-donor (D-A-D) conjugated molecules 1,4- bis(diarylaminophenylethynyl)anthraquinone (1,4-Am2Aq) and 1,4-bis(ferrocenylethynyl)anthraquinone (1,4-Fc2Aq), undergo a double proton cyclization reaction with bis(trifluoromethanesulfone)imide acid (TFSIH) to yield 1,4-bis(diarylaminophenyl or ferrocenyl) dipyrylium salts [1,4-R 2Pyl2](TFSI)2 (R=Am or Fc) with novel planar pentacyclic structures similar to the aromatic benzo[e]pyrene-type skeleton. [1,4-Am2Pyl2](TFSI)2 could be reduced to give the neutral molecule [1,4-Am2Pyl2]0, which is stable and maintains the benzo[e]pyrene-type skeleton.
