Construction of efficient blue AIE emitters with triphenylamine and TPE moieties for non-doped OLEDs

In this paper, by merging the hole-dominated triphenylamine (TPA) and tetraphenylethene (TPE) moieties together with different linkage positions, four derivatives of 1,2-bis[4′-(diphenylamino)biphenyl-4-yl]-1,2- diphenylethene (2TPATPE) were successfully synthesized with confirmed structures, and their thermal, optical and electronic properties were fully investigated. Thanks to the introduction of the meta-linkage mode on the TPE core, their π-conjugation length could be effectively restricted to ensure blue emission. The non-doped OLEDs based on these four emitters exhibit blue emissions from 443-466 nm, largely blue-shifted with respect to the green emission of 2TPATPE (514 nm). Meanwhile, good electroluminescence efficiencies with Lmax, ηC,max, and ηP,max of up to 8160 cd m-2, 3.79 cd A-1, and 2.94 Im W-1 respectively, have also been obtained, further validating our rational design of blue AIE fluorophores.

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.
