Issue Date: | 2009 | Journal Volume: | 19 | Journal Issue: | 22 | Start page/Pages: | 3618-3623 | Source: | Journal of Materials Chemistry | Abstract: | We have synthesized and characterized a novel thermally polymerizable triaryldiamine monomer (VB-FNPD) possessing a styrene-functionalized 9,9-diarylfluorene core and have used time-of-flight transient photocurrent techniques to investigate the hole transport properties of its solution-processed and subsequently thermally cured (170 °C) polymer films. 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. |
