An electrical and optical energy gaps separation strategy is put forward for the design of organic wide bandgap semiconductors. This new principle could achieve optimization of wide bandgap (both high singlet and triplet energies) and favorable carrier injection energy levels simultaneously.
Novel aryl phosphine organic photoelectric material based on carbazole unit as core and preparation method and application thereof

Paragraph 0021, (2019/11/20)
The invention discloses a novel aryl phosphine organic photoelectric material modified by tetraphenylsilane base on a carbazole unit as cores. By combination of the advantages of phosphine group and silicon-based photoelectric functional materials, the carbazole is used as the core, and a diphenylphosphine oxide/sulfur unit and a tetraphenylsilane unit are connected to the carbazole center core toobtain two materials DPOSi and DPSSi with excellent photoelectric properties. Blue light phosphorus photoelectric electroluminescent devices (PhOLEDs) prepared by the two materials have higher deviceproperties, and the highest external quantum efficiency reaches 20.8%.
