| | 4TCzBN Usage And Synthesis |
| Description | 4TCzBN is a derivative of carbazol benzonitrile. Its fluorescence peak is located at 456nm, and a new host-σ-guest emitter can be synthesized by grafting with host molecules to improve device performance. It is often used in either white or blue highly efficient TADF-OLED devices. | | References | [1] ;Liu D, et al.
