Abstract

Organic long-persistent luminescence (LPL) materials can overcome the disadvantages of inorganic LPL materials in terms of element sustainability, processability, and color tunability. However, all published electron donor/acceptor binary organic LPL systems show green emission. Here, we report an organic LPL system consisting of N,N,N¤,N¤-tetrakis(p-diisobutylaminophenyl)-p-phenylenediamine (TBAPD) as a donor dopant and 2,8-bis(diphenylphosphoryl)dibenzo[b,d]thiophene (PPT) as an acceptor host. The TBAPD/PPT film exhibits orange photoluminescence (CIE_x, CIE_y = 0.49, 0.49) and LPL (CIE_x, CIE_y = 0.51, 0.48).
