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.
一类用于有机电子器件（如有机发光二极管（OLED）或光折变全息存储器件）的新型空穴传输聚合物已被合成。这些聚合物在聚合物主链中包含四芳基联苯胺或四芳基苯二胺作为电荷传输单元，并通过非共轭芴桥连接。为用于OLED，新型聚合物用氧杂环丁烷基团进行功能化，这些基团可通过阳离子开环聚合进行交联，以产生不溶性网络。这种不溶性薄膜对于通过湿法沉积技术制造多层器件是必需的。如在绿色发光双层OLED中所展示的，这些新型材料具有改善的成膜性能。
