An electrooptic device and a surface modified electrode comprising a reduced organic material are provided. The reduced organic materials lower the work function of an electrode surface; they are also electro-active. These capabilities facilitate their use in production of more efficient electrooptic devices. The electrooptic device has at least a first conductive layer, a second conductive layer, and an electro-active layer comprising the reduced organic material disposed between the first and second conductive layers. The surface modified electrode comprises at least one conductive layer and at least one reduced organic material disposed upon a surface of said conductive layer. Methods for using the organic electro-active material for producing electrooptic devices, and operating the electrooptic devices are also disclosed. Coating compositions and coated articles comprising the reduced organic materials are also provided.

摘要:
The invention includes embodiments that relate to a method of making an organic light-emitting device comprising at least one bilayer structure. The method comprises providing at least one first layer comprising at least one cross-linkable organic material and at least one photo acid generator; exposing the first layer to a radiation source to afford a cross-linked first layer; and disposing at least one second layer on the cross-linked first layer. The method affords a bilayer structure having an enhanced structural integrity relative to the corresponding bilayer structure in which the first layer is not cross-linked. The invention also includes embodiments that relate to an organic light emitting device.

A light-emitting device comprises a light-emitting member, which comprises two electrodes, at least two organic electroluminescent (“EL”) materials disposed between the electrodes, a charge blocking material disposed between the electrodes, and at least one photoluminescent (“PL”) material. The light-emitting member emits electromagnetic (“EM”) radiation having a first spectrum in response to a voltage applied across the two electrodes. The PL material absorbs a portion of the EM radiation emitted by the light-emitting member and emits EM radiation having second spectrum different than the first spectrum. Each of the organic EL materials emits EM radiation having a wavelength range selected from the group consisting of blue and red wavelength ranges.
