Copolymers with a triscarbazole hole‐transport group and an oxetane or benzocyclobutene crosslinkable group can be readily thermally crosslinked on timescales of 30 min or less, with rapid thermal processing (RTP) being highly effective for this purpose. Devices with RTP‐crosslinked hole‐transport layers and spin‐coated emissive layers exhibit high external quantum efficiencies of up to 15%.
