Process and materials for making contained layers and devices made with same
View Patent ↗There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer including a fluorinated material and a photoinitiator, and having a first surface energy; treating the first layer with a priming layer including an aromatic amine compound; exposing the priming layer patternwise with activating radiation, resulting in exposed areas and unexposed areas; developing the priming layer to effectively remove the priming layer from the unexposed areas resulting in a first layer having a patterned priming layer, wherein the patterned priming layer has a second surface energy that is higher than the first surface energy; and forming the second layer by liquid deposition on the patterned priming layer on the first layer.
1. A process for forming a contained second layer over a first layer, said process comprising:
forming the first layer comprising a fluorinated material and a photoinitiator, said first layer having a first surface energy;
treating the first layer with a priming layer consisting essentially of an aromatic amine compound;

developing the priming layer to effectively remove the priming layer from the unexposed areas resulting in a first layer having a patterned priming layer thereon, wherein the patterned priming layer has a second surface energy that is higher than the first surface energy; and
forming the second layer by liquid deposition on the patterned priming layer on the first layer.
2. A process for making an organic electronic device comprising a support having thereon an electrode, a first organic active layer, and a second organic active layer, said process comprising
forming the first organic active layer over the electrode, said first organic active layer comprising a fluorinated material and a photoinitiator, and said first organic active layer having a first surface energy;
treating the first organic active layer with a priming layer consisting essentially of an aromatic amine compound;
exposing the priming layer patternwise with activating radiation, resulting in exposed areas and unexposed areas;
