摘要 |
<p>Use of certain materials in hole injection layer and/or hole transport layer can improve operational lifetimes in organic devices. Polymers having fused aromatic side groups such as polyvinylnaphthol polymers can be used in conjunction with conjugated polymers. Inks can be formulated and cast as films in organic electronic devices including OLEDs, SMOLEDs, and PLEDs. One embodiment provides a composition comprising- at least one conjugated polymer, and at least one second polymer different from the conjugated polymer comprising at least one optionally substituted fused aromatic hydrocarbon side group. The substituent can be hydroxyl. Aqueous-based inks can be formulated.</p> |
