units was prepared and characterized. The new system readily assembles and forms at least two stable
charge-transfer crystalline structures having a thermal population of unpaired electrons. The crystals of
one phase exhibit electrical bistability, displaying either high (ON) and low (OFF) conductivity, at the same
applied bias, depending on the electrical history of the system. The relation between the supramolecular
structure of the crystals and their electrical properties is also discussed.
