Combining a carbazole electron donor with high triplet energy, and a pyridine electron acceptor with high electron affinity, 3,5-bis(3-(carbazol-9-yl)phenyl)pyridine (35DCzPPy) is one of the most common bipolar host materials used in organic light-emitting diodes.
35DCzPPy is an isomer of 26DCzPPy, differing in the position of functionalisations of the central pyridine ring. 35DCzPPy is more electron-rich, so 26DCzPPy has a more balanced hole and electron injection and transport than 35DCzPPy.
Bipolar host materials are the molecules composed of an electron-donating moiety, capable of mediating hole injection and transportation; and an electron-withdrawing moiety capable of mediating electron injection and transportation.
