3,3'-Bicarbazole, Bicarbazole derivative

A useful building block for the synthesis of hole transport layer, host, TADF emitting layer materials in application of organic light-emitting devices and perovskite solar cells.

Specifications | MSDS | Literature and Reviews

3,3'-Bicarbazole (CAS number 1984-49-2) is a bicarbazole derivate that is formed by joining two carbazole units at 3,3'-positions. Bonding at 3,3'-positions not only extends the conjugation of each individual carbazole units but also improves the stability by partially blocking the electron active sites at 3,3'-positions.

As a bipolar charge transporting material derived from 3,3‘-bicarbazole, triphenylsilyl-substituted 3,3‘-bicarbazole, was found to be a good phosphorescent host that is competitive with the widely used host mCP. Warm-white-emissive device exploring 9-(9,9’-spirobi[fluoren]-3-yl)-9’-phenyl-9H,9’H-3,3’-bicarbazole (SFBCz) as one of the exciplex-forming hosts, a blue TADF-sensitizer 5TCzBN, and a yellow fluorescent dopant TBRb in a single-emissive-layer demonstrated an external quantum efficiency of 21.4%, a benchmark PE of 69.6 lm W-1, and a remarkable T80 of >8200 h at 1000 cd m-2.

Highly efficient and stable perovskite solar cells using the p–i–n device structure ITO/NiOx/NP-BC/perovskite/PC61BM/BCP/Ag achieved an overall PCE of almost 20%. NP-BC is 3,3′-bicarbazole-based hole transporting material 9,9'-Diphenyl-9H,9'H-3,3'-bicarbazole, also named as BczPh.
