Abstract

Three bipolar materials, 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-N,N-diphenylaniline (DPAT-Ph), 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-N,N-diphenylnaphthalen-1-amine (DPAT-Na), and 10-(4,6-diphenyl-1,3,5-triazin-2-yl)-N,N-diphenylanthracen-9-amine (DPAT-An), were designed and synthesized. To achieve a bipolar character, diphenylamine (DPA) moiety and 2,4-diphenyl-1,3,5-triazine (DPT) moiety were introduced as electron donating and electron accepting groups, respectively. The three compounds exhibited UV maximum wavelengths (UV_max) at 395–454 nm and photoluminescence maximum wavelengths (PL_max) at 472–546 nm. 10-(4,6-Diphenyl-1,3,5-triazin-2-yl)-N,N-diphenylanthracen-9-amine (DPAT-An) shows AIE phenomenon even though DPAT-An does not have tetraphenylethylene (TPE) moiety which is representative AIE structure. DPAT-An exhibits over EQE value of 5% and long device lifetime of 1310 h without sublimation process.
