Application

4,4′-Bis(carbazol-9-yl)biphenyl can be used as a as a hole transport material or as part of the active layer inorganic photovoltaics (OPVs) devices. Due to its semiconducting properties, it can be used as a charge transport material in Organic Field-Effect Transistors(OFETs).It can be utilized as a host material in the emissive layer of organic light-emitting diodes (OLEDs) devices. It provides a suitable matrix for efficient energy transfer from dopant molecules, leading to enhanced electroluminescence and color purity in OLEDs.
4,4′-Bis(carbazol-9-yl)biphenyl, also known as CBP is used as solution-processable Phosphorescent Host in organic electronics such as OLED devices.

Simultaneously achieving high efficiency and low efficiency roll-off remains a big challenge for OLEDs based on thermally activated delayed fluorescence (TADF) emitters. To address this issue, we elaborately designed and synthesized a series of new emitters with both TADF and

Developing red thermally activated delayed fluorescence (TADF) emitters, attainable for both high-efficient red organic light-emitting diodes (OLEDs) and non-doped deep red/near-infrared (NIR) OLEDs, is challenging. Now, two red emitters, BPPZ-PXZ and mDPBPZ-PXZ, with twisted donor-acceptor structures were designed and synthesized

The combination of rigid acridine donor and 1,8-naphthalimide acceptor has afforded two orange-red emitters of NAI-DMAC and NAI-DPAC with high rigidity in molecular structure and strongly pretwisted charge transfer state. Endowed with high photoluminescence quantum yields (ΦPL ), distinct thermally
