简单介绍


ossila材料DTAF  的详细介绍

DTAF has a fluorene centered structure with two N,N-bis(p-tolyl))benzenamine attached to the fluorine. DTAF is electron rich, so is normally used as a hole transporting layer or electron blocking layer (with a LUMO of 1.84 eV) in OLED devices.

DTAF can also form exciplexes with other electron deficient materials, such as PO-T2T, generating yellow exciplex emission. Parallel all exciplex based white-light OLED (WOLED) blend layers of mCP/PO-T2T and DTAF/PO-T2T demonstrates excellent maximum current and power efficiencies (27.7 cd/A and 15.8 ml/W respectively) with CIE(0.29, 0.35) and CRI 70.6 [1].
