Recently, bipolar host materials have attracted considerable attention because they can achieve balanced charge injection/transport in phosphorescent organic LEDs (PhOLEDs) and consequently obtain excellent device performance. Two bipolar host materials, namely, 3-(4,6-diphenyl-1,3,5-triazin-2-yl)-9-phenyl-9H-carbazole (DPTPCz) and 3-(4,6-diphenoxy-1,3,5-triazin-2-yl)-9-phenyl-9H-carbazole (DPOTPCz), were designed, synthesized, and characterized. With high triplet energy levels of 2.78 and 2.86 eV for DPTPCz and DPOTPCz, resp., 2 compounds are considered promising bipolar host materials for PhOLEDs. Blue and green PhOLEDs based on these 2 new compounds show excellent performances. The phosphorescent devices based on DPTPCz exhibit maximum external quantum efficiencies of 14.4% (for blue device) and 21.2% (for green device), and maintain high efficiencies of 11.9% and 20.0% even at a high luminance of 10,000 cd m^-2.

Xiao, J. published the artcileHighly efficient green and red phosphorescent OLEDs using novel bipolar blue fluorescent materials as hosts, HPLC of Formula: 1313391-57-9, the publication is Synthetic Metals (2014), 89-93, database is CAplus.

The authors studied highly efficient green and red phosphorescent organic light-emitting diodes (OLEDs) based on two kinds of Ir complexes as the guests and two novel 1,3,5-triazine derivatives as the host materials, resp. For comparison, the devices using a common fluorescent host 4,4′-N,N’-dicarbazolebiphenyl (CBP) also were fabricated. All devices using 1,3,5-triazine derivatives as host have better performance than that of CBP. This may be attributed to the adoption of the hosts, which have suitable HOMO/LUMO levels enabling excitons to form on host and hence favoring efficient energy-transfer from host to guest. The high bipolar carrier mobility of the host is critical to this kind of doping system, which would balance the injection of both carriers and improve efficiency.
