Because of its interesting possibilities organic electronics has recently gained tremendous attention among researchers. New polymers and conjugated molecules are being synthesized and studied for organic electronic applications. Here we are reporting a bilayer organic bistable memory device based on a pyrrolo-pyrrole derivative, 3,3'-(5',5'''-(2,5-bis(2-ethylhexyl)-3,6-dioxo-2,3,5,6-tetrahydropyrrolo[3,4-c]pyrrole-1,4-diyl)bis([2,2'-bithiophene]-5',5-diyl))bis(2-(4-nitrophenyl) acrylonitrile) (PPbAN) which is highly conjugated and having the donor property. A known and widely used acceptor methano fullerene, [6,6]-phenyl C61 butyric acid methyl ester (PCBM) has been used as the acceptor. Device fabrication is carried out on an Indium tin oxide substrate by spin coating technique, aluminum is used as the top electrode. The device exhibited good bistabilty with a low conducting state having thermionic emission behavior and a high conductivity state following ohmic nature..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
