Kailong Wu et al.
The journal of physical chemistry letters, 9(7), 1547-1553 (2018-03-07)
Two new blue emitters, i.e., bis-[2-(9,9-dimethyl-9,10-dihydroacridine)-phenyl]-sulfone ( o-ACSO2) and bis-[3-(9,9-dimethyl-9,10-dihydroacridine)-phenyl]-sulfone ( m-ACSO2), with reserved fine thermally activated delayed fluorescent (TADF) nature and simply tuned thermal and optoelectronic properties, were synthesized by isomer engineering. The meta-linking compound, i.e., m-ACSO2, obtains the

Advanced materials (Deerfield Beach, Fla.), 26(30), 5198-5204 (2014-06-07)
Thermally activated delayed fluorescence emitters with small energy gap between the triplet and singlet (ΔEST ), TXO-PhCz and TXO-TPA, have been successfully synthesized by combining a hole-transporting TPA/PhCz moiety and an electron-transporting TXO moiety. Both compounds display efficient solid-state luminescence
Huijun Liu et al.
Angewandte Chemie (International ed. in English), 57(30), 9290-9294 (2018-06-02)
Non-doped organic light-emitting diodes (OLEDs) possess merits of higher stability and easier fabrication than doped devices. However, luminescent materials with high exciton use are generally unsuitable for non-doped OLEDs because of severe emission quenching and exciton annihilation in neat films.
Meng Li et al.
Angewandte Chemie (International ed. in English), 57(11), 2889-2893 (2018-01-23)
Aromatic-imide-based thermally activated delayed fluorescent (TADF) enantiomers, (+)-(S,S)-CAI-Cz and (-)-(R,R)-CAI-Cz, were efficiently synthesized by introducing a chiral 1,2-diaminocyclohexane to the achiral TADF unit. The TADF enantiomers exhibited high PLQYs of up to 98 %, small ΔEST  values of 0.06 eV, as well
Wei Li et al.
Angewandte Chemie (International ed. in English), 58(2), 582-586 (2018-11-21)
To date, blue dual fluorescence emission (DFE) has not been realized because of the limited choice of chemical moieties and severe geometric deformation of the DFE emitters leading to strong intramolecular charge transfer (ICT) with a large Stokes shift in
