- A new approach to prepare efficient blue AIE emitters for undoped OLEDs
-
Two aggregation-induced emission active luminogens (TPE-pTPA and TPE-mTPA) were successfully synthesized. For comparison, another six similar compounds were prepared. Because of the introduced hole-dominated triphenylamine (TPA), fluorene groups with high luminous efficiency, and unconjugated linkages, the π conjugation length of the obtained luminogens is effectively restricted to ensure their blue emission. The undoped organic light-emitting diodes based on TPE-pTPA and TPE-mTPA exhibited blue or deep-blue emissions, low turn-on voltages (3 V), and high electroluminescence efficiencies with Lmax, ηC,max, and ηP,max values of up to 26 697 cd m-2, 3.37 cd A-1, and 2.40 Lm W-1. By adding the hole-dominated triphenylamine (TPA) and fluorene groups with high luminous efficiency to the tetraphenylethene (TPE) moiety through unconjugated linkages, the π conjugation lengths of the fluorophores are effectively restricted to ensure deep-blue emission. Two of the undoped OLEDs exhibit blue and deep-blue emissions with good electroluminescence efficiencies.
