Kautny, Paul published the artcileOxadiazole based bipolar host materials employing planarized triarylamine donors for RGB PHOLEDs with low efficiency roll-off, Safety of 4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-ol, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2014), 2(11), 2069-2081, database is CAplus.

6 Novel triarylamine-containing oxadiazole compounds (o-PCzPOXD, o-ICzPOXD, o-TPATOXD, o-PCzTOXD, o-ICzTOXD, o-CzTOXD) were designed, synthesized and characterized concerning applications as host materials in PHOLED devices. To further improve the ortho-linkage concept, the impact of incorporating planarized electron-donating triarylamine (TAA) structures on intramol. charge transfer was examined The effect was evaluated for 2 series of electron-accepting oxadiazole scaffolds, realizing ortho-linkage on the benzene (POXD) and the thiophene (TOXD) cores. Thermal anal. shows increased glass-transition temperatures for planarized structures indicating an improved morphol. stability. A higher degree of planarization also results in significantly increased singlet and triplet energy values, revealing the impact on the intramol. charge transfer. Using the developed materials, red (o-TPATOXD: CEmax: 28.8 cd A-1, EQEmax: 16.9%), green (o-PCzPOXD: CEmax: 62.9 cd A-1, EQEmax: 17.1%) and blue (o-PCzPOXD: CEmax: 29.8 cd A-1, EQEmax: 13.4%) devices were achieved showing remarkably low efficiency roll-off for planarized donors. This is the 1st report of efficient blue devices for this specific class of host materials. Probably the results correlate with an increasing ortho-linkage effect and decreasing donor strength of the TAA moiety by planarization and, thus, tackling 1 of the major challenges in PHOLED research: improving both triplet energy and compound stability.
