9,9-(2,6-pyridinediyl)bis-9H-carbazole Usage And Synthesis

Description

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.

Uses

A highly efficient host material for blue phosphorescent OLEDs.
