A remarkable development of charge transfer (CT) com- plexes and CT salts based on tetrathiafulvalene (TTF) type do- nors is continuing to attract considerable interest in the fields of organic conductors and superconductors.1 One of the most difficult challenges is the creation of donor molecules which have a new skeleton with relatively low oxidation potentials. We have designed and synthesized 1,6-dithiapyrene (DTPY) and its derivatives for new donor molecules (Chart 1).2,3 The CT ...
