• Beschreibung

  2,6-bis(3-(9H-carbazol-9-yl)phenyl)pyridine, also named DCzPPy, is a bipolar host material. It has high triplet energy, carrier mobilities, and deep highest occupied molecular orbital (HOMO) level . The host system was prepared by mixing the hole-transport-type host 4,4,4-tris(N-carbazolyl)triphenylamine with the electron-transport-type host 2,6-bis(3-(carbazol-9-yl)phenyl)pyridine to prepare the host system, which could not only improve CRI but also improve device efficiency[1-2].
