  • Patent number: 7276298
    Abstract: The present invention is related to an intermediate layer of an organic electroluminescent device comprising an amine derivative substance which may further comprise a functional group capable of forming crosslinks. In particular, the substance may have excellent solubility and can be easily formed into a thin film. Specifically, the thin film may be stable in the solvent and can be easily formed to various thicknesses. Furthermore, the band gaps and LUMO/HOMO values may be easily controlled depending of the characteristics of the hole transporting material, so that an intermediate layer with the desired characteristics may be formed. Accordingly, the introduction of an intermediate layer manufactured using the substance of the present invention as the intermediate layer may result in an organic electroluminescent device having high efficiency and a longer lifespan.

  • Patent number: 7175961
    Abstract: Bistable molecules are provided with at least one photosensitive functional group. As thus constituted, the bistable molecules are photopatternable, thereby allowing fabrication of micrometer-scale and nanometer-scale circuits in discrete areas without relying on a top conductor as a mask. The bistable molecules may comprise molecules that undergo redox reactions, such as rotaxanes and catenanes, or may comprise molecules that undergo an electric-field-induced band gap change that causes the molecules, or a portion thereof, to rotate, bend, twist, or otherwise change from a substantially fully conjugated state to a less conjugated state. The change in states in the latter case results in a change in electrical conductivity.
