2,6-Bis(9H-carbazol-9-yl)pyridine (PYD-2Cz) is composed of two electron-donating carbazole substituents with an electron deficient pyridine core unit. PYD-2Cz is a commonly-used bipolar host material for phosphorescent organic light‐emitting diodes (PHOLEDs). This is due to its wide band-gap and ability to be both an electron acceptor and donor.
With higher triplet energy levels (T1 = 2.93 eV), PYD-2Cz is an ideal candidate for hosting blue electrophosphorescence OLEDs.
*Sublimation is a technique used to obtain ultra pure-grade chemicals. For more details about sublimation, please refer to the Sublimed Materials for OLED devices page.
