NANOSTRUCTURED ORGANIC MATERIALS - COPPER-TCNQ AND SILVER-TCNQ RADICAL SALTS

Using a solid slate diffusion technique, conducting tetracyanoquinodim ethane (TCNQ) radical ion sail films have been prepared with Cu and Ag counterions on glass substrates. Some features of organic conductors, e.g. transport properties of reduced dimensionality, motivate to pres erve the anisotropy in films, which additionally can be structured in dimensions below some hundred nanometers. This requires films consisti ng of crystallites with an average size of less than 50 nm as realized in vacuum deposited Cu- and Ag-TCNQ films. The processing of striplin es of CuTCNQ is reported.
