UGH3, 1,3-bis(triphenylsilyl)benzene, is an isomer to UGH-2, 1,4-bis(triphenylsilyl)benzene.
UGH3 is an ultrahigh energy gap (4.40 eV) organosilicon compounds and a weak electron-transport-type host for highly efficient blue PHOLEDs. UGH3 has a high triplet energy (ET=3.1 eV) and can also be used as a host material to dilute exciplex, to enhance TADF-OLED optical and electrical device performance. Having a deep HOMO energy level (7.2 eV), UGH3 can also be used as an effective hole blocking layer material.
Both UGH2 and UGH3 have low glass transition temperatures (Tg) below 100 °C. BSB, 4,4'-di(triphenylsilyl)-biphenyl, however, offers better morphology of OLED device films for higher device performance and stability with higher Tg at 100 °C.
