摘要:
Conjugated polymers containing ansa substructures and their use as electroluminescence materials. Conjugated polymers containing ansa substructures, which contain aromatic groups and in which adjacent aromatic groups are connected to one another in such a way that one ring atom of one aromatic group is directly linked to one ring atom of the other aromatic group and any further linkages of these two aromatic groups are possible only via a bridge containing at least one tetravalent carbon atom and/or heteroatom. The polymers of the invention having ansa substructures are outstandingly suitable as electroluminescence materials, since they have a very high color purity.

Use in electrooptical switching and display devices of a polymer comprising conjugatively linked chromophore segments whose emission properties are determined by the emission properties of the individual chromophore segments.Electroluminescence devices comprising the polymers of the present invention have, inter alia, a high color purity. The polymers used according to the present invention enable, in particular, blue and white electroluminescence to also be achieved.
摘要:
The present invention relates to polymers with an extended system of conjugated double bonds constructed as homo and/or heterocyclic rings which are interlinked in pairs so that one ring is joined to the neighboring one at two adjacent atoms in the ring, in which one of these connections is made by a chemical bond to a ring atom of the neighboring ring and the other via a carbon, nitrogen, oxygen or sulphur atom to an atom of the neighboring ring adjacent said ring atom, their production and use in electrical, electronic and opto-electronic components.

摘要:
A method to produce nonlinear optical microcomponents is described which employs hitherto not yet used material combinations. Not only waveguide structures are produced by means of X-ray depth lithography, but also microcell structures, into which materials having nonlinear optical properties are introduced. The microstructure is produced as a positive mold part, from which there is subsequently generated, by means of electroforming, a mold insert, a negative of which is made using a polymer material. After the molding operation the microstructure is applied to a substrate, and nonlinear optical material, covered by a cover plate if needed or desired, is introduced into the microcell structure.

摘要:
A method to produce nonlinear optical microcomponents is described which makes it possible to employ material combinations not yet used to date. By means of X-ray depth lithography not only waveguide structures, but also microcell structures are produced, into which subsequently material of nonlinear optical properties is placed. By means of X-ray depth lithography and micromolding techniques a mold insert with a waveguide structure is produced as a positive mold, and the waveguide structure is impressed into a polymer base material by means of the mold insert. Then the impressed waveguide structure is filled with optically linear material, and after the filling operation at least one microcell structure is produced, at least in the areas of the optically linear material, into which microcell structure optically nonlinear material is placed. The microcell structure may also be impressed by means of another mold insert.

The present invention relates to an optically transparent conductive carbon-based film which is suitable for use as an electrode in optoelectronic devices etc. Further, the invention relates to a process for the production of the transparent conductive carbon film and the use thereof in electronic devices. Organic solar cells using transparent conductive carbon film as electrode display comparable performance with cells using ITO. These carbon films show high thermal and chemical stability, ultra-smooth surface, and good adhesion to substrates.
