Abstract: The charge transfer apparatus of the present invention comprises an optical storage medium of either a mixture of several charge transfer compounds of varying redox potential or a single amphoteric organic charge transfer compound capable of undergoing a multistage charge transfer reaction, and a source of optical energy, typically a laser. When the optical energy illuminates a spot on the optical storage medium, the spot switches to one of a plurality of optically detectable states.

Abstract: Optical devices using an organic charge transfer salt as the switching and storage media are disclosed. Generally, a light beam of a given intensity directed to a film of certain organic charge transfer salts causes the illuminated area to change from a first to a second state. This electrochemical process is reversible with heat energy transforming the illuminated area back into the first state. The first and second states have identifiably different optical and electrical properties. The organic charge transfer salt is used to fabricate an erasable or permanent optical memory and a threshold on bistable optoelectronic switch.

Abstract: An enhanced optically sensitive medium is disclosed which uses an organic charge transfer complex as the switching material. The organic charge transfer complex includes at least one moiety in an oxidized state. An enhancement mechanism is taught which provides a secondary source of neutral molecules of said at least one constituent moiety in the neutral or altered oxidation state. For example, with CuTCNQ used as the switching material, the erasing characteristics can be improved by using a covering dispersion having a matrix polymer interspersed with neutral molecules of TCNQ.degree..

Abstract: A multistate organic optical storage medium is disclosed, wherein an optical beam can switch any "data storage spot" on said optical storage medium into three or more memory states. The optical storage medium may consist of a mixture of bistate switching modules, or it may consist of large delocalized amphoteric molecules. The illuminated area of said optical storage medium will undergo an electrochemical topactic redox reaction which will cause certain moieties in the illuminated area to change oxidation state. By changing the intensity of the optical "write" beam the illuminated area can be switched to a plurality of specific states each state having a unique set of oxidation species. An optical/spectroscopic means is used to identify the presence of oxidation species and to "read" the data stored.

Abstract: A current-controlled, bistable threshold or memory switch comprises a polycrystalline metal-organic semiconductor sandwiched between netallic electrodes. Films of either copper or silver complexed with TNAP, DDQ, TCNE, TCNQ, derivative TCNQ molecules, or other such electron acceptors provide switching between high and low impedance states with combined delay and switching times on the order of 1 nanosecond. Switching behavior of a complex of the present invention is related to the reduction potential of the acceptor molecule.
