This novel polymeric material exhibits non-dispersive hole transport behavior with a high hole drift mobility (up to 10-4 cm2 V -1 s-1). The film displayed remarkable ambient stability, even when exposed to air for one month. We tested the thermally generated polymer film as a hole transport material in organic light-emitting diodes incorporating tris(8-hydroxyquinolate) aluminium (Alq3) as the emission and electron transport layer. The device exhibited a maximum external quantum efficiency (ηex) of 1.4%, significantly better than that of the device prepared using the corresponding model compound VB-model (ηex = 1.1%). © 2009 The Royal Society of Chemistry.application/pdf2174145 bytesapplication/pdfAmbient stability; Electron transport layers; External quantum efficiency; Functionalized; Hole drift-mobility; Hole transport materials; Hole transports; Model compound; Polymeric material; Solution-processed; Time of flight; Transient photocurrents; Curing; Functional polymers; Hole mobility; Light emitting diodes; Organic light emitting diodes (OLED); Plastic films; Polymers; Styrene; Transport properties; Polymer filmsjournal article10.1039/b900977a2-s2.0-66249145735WOS:000266410900009
