NOVELTY - A composition comprises mixture of non-polymeric compound exhibiting single thermal transition free of phase separation and at least two different compounds in which each different compound contains at least two linking components. Each linking component joins one multivalent organic nucleus with at least two organic nuclei in which at least one of the multivalent organic nuclei and organic nuclei contain crosslinkable groups and/or polymerizable groups. The mixture is amorphous and solid at 20 degrees C.    USE - Composition is used for forming organic films e.g. light-emitting film of organic device e.g. organic light emitting diode display, organic light emitting diode luminaire, organic solar cell and organic thin film transistor (all claimed). Uses include but are not limited to field-effect transistors, solar cells, luminescent devices, and photorefraction device.    ADVANTAGE - The composition forms film for fabrication of organic device without solvent coating of multiple thin layers and without need for photolithography and etching of organic film.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of organic device, which involves providing a substrate, providing set (a) of addressing electrodes on the substrate, forming an organic hole-transporting layer on the set (a) of addressing electrodes and substrate, forming an organic light-emitting layer comprising crosslinkable organic light-emitting layer and polymerizable organic light-emitting layer and having glass transition temperature of less than 80 degrees C, on the organic hole-transporting layer, forming a dopant layer on the organic light-emitting layer, patterning the dopant layer to form color pixels, subjecting the organic light-emitting layer to actinic energy to crosslink the organic light-emitting layer and polymerize the light-emitting layer, forming an organic electron-transporting layer on the doped organic light-emitting layer and forming set (b) of addressing electrodes on the organic electron-transporting layer.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic sectional view of organic light emitting device.
