简单介绍


ossila材料SiCzCz  的详细介绍

SiCzCz has a structure of an electron rich bicarbazole joined to a tetraphenylsilane onto one of the benzene rings. The bicarbazole donor unit introduced in SiCzCz can produce a shallower HOMO level compared to that of the mono-carbazole analogue to reduce the hole injection barrier between the adjacent hole transport layer and emitting layer.

SiCzCz can normally be used as the hole transport main layer for blue OLEDs. SiCzCz has been very successful to be used with the electron transport materials, i.e. SiTrzCz2 to form an exciplex host. It is believed that the introduction of triphenyl silicon unit can stabilize the excited state and polar state of the host material by participating in the conjugated system through the hyperconjugation effect. Blue PhOLED devices based on this material exhibit LT70 = 1113h.

SiCzCz is an isomer to SimCP thus share the closest molecular structure similarity with SimCP. They both can be used as host materials in OLED devices.
