CzAcSF is an unsymmetrical acridine derivative with one carbazole and one 9,9-dimethyl- 9,10-dihydroacridine attached to a diphenylsulfonyl centre. CzAcSF is normally used as blue TADF dopant for highly efficient TADF-OLED devices. A quantum efficiency of 18.1% [1] has been achieved at a doping concentration of 0.1% TBPe in active emitting layer of DPEPO:CzAcSF.

CzAcSF can also be used as a bipolar host material to harvest singlet excitons of TBPe dopant material by a Forster energy transfer process. BFOXD-based devices exhibit better performances, with a maximum external quantum efficiency (EQE) of 20.1% while using CzAcSF as the host [2].

We stock high purity (>99%) CzAcSF and a range of other TADF materials and semiconducting molecules for priority dispatch (lead times may apply for large quantities). Qualifying orders ship free.
