A new class of hole‐transporting polymers for use in organic electronic devices such as organic light‐emitting diodes (OLEDs) or photorefractive holographic storage devices has been synthesized. The polymers contain tetraarylbenzidines or tetraarylphenylenediamines as charge‐transporting units in the polymer backbone and are connected by non‐conjugating fluorene bridges. For use in OLEDs the novel polymers were functionalized with oxetane groups that can be cross‐linked via a cationic ring opening polymerization to yield insoluble networks. Such insoluble films are necessary for the fabrication of multilayer devices by wet deposition techniques. The novel materials feature improved film‐formation properties as demonstrated in green‐emitting double‐layer OLEDs.
