Nanoelectronics

“…Electrical measurements require a second electrode which is made by evaporation of a metal on top of the SAM. This is usually the most difficult task because the metal must not diffuse into the SAM where it could make short circuits [37]. In the same time, the contact resistance must be small which requires a good control of the metal/SAM interface.…”

Novel molecules for the design of organic conductors. Synthesis of 7,7,8,8-tetracyano-2,5-bis(3-phenylpropyl)-p-quinodimethane and N,N′-dicyano-2,5-bis(3-phenylpropyl)-p-quinodiimine and X-ray structure of the TCNQ derivative

“…A very promising application of these materials has been recently suggested as the basis for unimolecular devices containing a donor and an acceptor moiety linked by a chain in which a functional group is present. 3 Previously, the very interesting molecule 2,5-dibenzyl-7,7,8,8tetracyano-p-quinodimethane (DBTCNQ, 1) was synthesized and studied as a prototypical D-A-D system. Some derivatives containing substituents in the weakly donating phenyl ring were also included.…”
