The Simple Way to Solution-Processed Multilayer OLEDs - Layered Block-Copolymer Networks by Living Cationic Polymerization

Solution-processed multilayered OLEDs are fabricated through a conceptually novel, simple, intelligent, and cost-effective strategy, namely layer-by-layer cross-linking (LBLX). It enables the use of a wide range of conventional and low-priced wet deposition techniques (e.g., all printing techniques), and is based on PEDOT-initiated cross-linking of oxetane-functionalized polymers, which resembles the grafting-from approach.
