CAS.1637752-63-6 5-phenyl-5,8-dihydroindolo[2,3-c]carbazole

The indolocarbazole structure provides a wide range of conjugated systems, enabling the compound to exhibit excellent charge transfer ability. In OLED devices, charge transfer is a key factor determining the luminous efficiency. This compound can effectively promote the transport of electrons and holes, thereby enhancing the charge recombination efficiency of the luminescent layer and improving the luminescence efficiency. In addition, indolocarbazole compounds are commonly used as hole transport layer (HTL) materials in OLEDs due to their excellent hole transport capabilities. The hole transport layer in OLED helps optimize the injection and transport of electrons and holes, balance charges, and thereby improve the overall luminous efficiency of the device.
