Publication number: 20100145050Abstract: The present invention relates to chemical compounds that can be used in electrooptical applications. The electrically conductive and optical properties of these compounds, e.g. hole transporting, electron transporting and/or light emitting properties can be predetermined by substituting the core structure of these compounds with respective residues. The core structure (1) of the compounds according to the invention comprises two opposing aromatic moieties which are chemically bonded through an intermediate central atom. This central atom has a tetraedric configuration and therefore provides an orthogonal orientation to the organic moieties.Type: ApplicationFiled: January 10, 2005Publication date: June 10, 2010Applicant: TECHNISCHE UNIVERSITAT BRAUNSCHWEIGInventors: Hans-Hermann Johannes, Wolfgang Kowalsky, Martin Dümeland, Ulfla Wrenz

Patent number: 6951603Abstract: A two-layered anode (1?) has a lower layer (2) including a non-conductive carrier material to which a conductive electrode layer (3?) is applied. Non-conductive areas, formed by partial removal of the electrode layer, have a predetermined structure corresponding to the structure of a structured polymer film (11) to be formed. The anode (1?) is connected with a platinum cathode in an electrolyte into which compounds of low molecular weight, preferably monomers of the polymer film (11), are introduced. During current flow, a conductive polymer film (11) of the predetermined structure is formed on conductive areas brought into contact with the electrolyte. A non-conductive substrate layer (13) is applied to the structured polymer film (11). The structured polymer film (11) adheres to the non-conductive substrate layer (13) and can be released from the electrode (1?) without damaging the electrode.Type: GrantFiled: August 21, 2002Date of Patent: October 4, 2005Assignee: Technische Universitat BraunschweigInventors: Eike Becker, Hans-Hermann Johannes, Wolfgang Kowalsky
