Cyclic conjugation in benzo- and benzocyclobutadieno-annelated terrylenes and higher rylenes

摘要

The effect of benzo- and benzocyclobutadieno-annelation on cyclic conjugation in terrylene and the higher members of the rylene homologous series is examined. Some peculiar regularities are established, that could not be observed in the case of perylene (the first member of the rylene series).
