摘要:
Through-space charge transfer (TSCT) thermally activated delayed fluorescence (TADF) emitters typically exhibit relatively low radiative decay rate ( k r s ), which remains a formidable obstacle to further improving device efficiency and suppressing efficiency roll-off. Here, two novel deep-blue TSCT-TADF emitters (YCIT14 and YCIT15) were rationally developed. Both emitters feature 2,4-diphenyl-1,3,5-triazine (DPTRz) and 2,4,6-triphenyl-1,3,5-triazine (TPTRz) as acceptor (A) units, which are interconnected via a phenyl bridging structure with 9...
