Abstract
Official abstract text for this publication.
The present invention relates to novel compositions comprising light emitting materials and/or charge transport materials and a polymeric binder, to their use as conducting inks for the preparation of organic light emitting diode (OLED) devices, to methods for preparing OLED devices using the novel formulations, and to OLED devices prepared from such methods and formulations.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising one or more organic light emitting materials and/or charge transport materials having a molecular weight of at most 5000 g/mol, one or more organic solvents, and one or more polymers, wherein said polymer is an inert binder which does not have semiconducting properties and wherein the weight ratio of the one or more polymers to the one or more light emitting materials and/or charge transport materials is in the range of 1:2 to 1…
