New sulfur-containing host materials for blue phosphorescent organic light-emitting diodesElectronic supplementary information (ESI) available: DSC and mass spectra data for compounds B2tCz and DB2tCz. See DOI: 10.1039/c2jm34165d
Two novel host materials based on carbazole derivatives were synthesized with benzo[ b ]thiophene (B2tCz) or dibenzothiophene (DB2tCz) for use in evaporation-processed blue phosphorescent organic light-emitting diodes. Both host materials exhibited high glass transition temperatures ( T g = 179 °C f...

]thiophene (B2tCz) or dibenzothiophene (DB2tCz) for use in evaporation-processed blue phosphorescent organic light-emitting diodes. Both host materials exhibited high glass transition temperatures (
T

= 179 °C for B2tCz and
T
g
= 185 °C for DB2tCz) and triplet energy levels (
E
T
= 2.84 eV for B2tCz and
E
T
= 2.93 eV for DB2tCz). Multilayer devices fabricated using B2tCz or DB2tCz as hosts for the phosphorescence emitter, iridium(

, power efficiencies of 34.0 and 29.4 lm W

, and external quantum efficiencies of 24.6% and 20.0%, respectively.
Two phosphorescent blue host materials with sulfur-containing ring moieties were successfully utilized for use in evaporation-processed organic light-emitting diodes (OLEDs). |
