We demonstrate the synthesis and use of a new class of EL polymers, which can be applied similar to a standard photoresist. Soluble poly‐spiros with oxetane sidegroups were crosslinked photochemically to yield insoluble polymer networks in the desired areas with μm resolution. Consecutive deposition...

Zusammenfassung:We demonstrate the synthesis and use of a new class of EL polymers, which can be applied similar to a standard photoresist. Soluble poly‐spiros with oxetane sidegroups were crosslinked photochemically to yield insoluble polymer networks in the desired areas with μm resolution. Consecutive deposition of the three colors yielded an RGB device with efficiencies and lifetimes comparable to state‐of‐the‐art EL polymers.
