A consortium of eleven partners led by Merck has concluded a three-year research project into new solution-processable materials for organic light-emitting diodes (OLEDs). The New materials for OLEDs from solutions (NEMO) project had an overall budget of approximately $37 million and was co-funded by the German Federal Ministry of Education and Research. The focus has been on materials that are especially suited for printing processes. The scope of the project extended from soluble light-emitting materials and charge-transport materials to new adhesives for reliable encapsulation of each OLED component. DELO Industrie Klebstoffe worked on the development of adhesives with low water vapor permeation for flat encapsulation. A main focus of the work was on optimizing the compatibility of the adhesive with the OLED materials. Suitable adhesive systems were identified, and a significant reduction in component defects was achieved.
