Abstract
Functional devices using charge transfer complexes formed as a layer on a substrate. In one embodiment of the invention, the device comprises a substrate, an electrode layer formed on one side of the substrate, at least one layer of a charge transfer complex capable of undergoing a variation in charge transferability by application of external energy, and another electrode layer formed on the complex layer. The charge transfer complex consists essentially of an electron donor and an electron acceptor, at least one of which is an organic compound having a long-chain alkyl substituent. In another embodiment, a charge transfer complex layer is provided on a substrate as polarized in one direction, in which the charge transfer complex does not necessarily contain such a substituted donor or acceptor compound as in the first embodiment but ordinary charge transfer complexes may be used. A pair of electrodes may be provided to sandwich the complex layer therebetween.
