| description | A series of phosphine oxide hosts, 4,6-bis(diphenylphosphoryl) dibenzothiophene (
DBTDPO
) and 4- diphenylphosphoryldibenzothiophene (
DBTSPO
) and electron transporting materials (ETM), 2-(diphenylphosphoryl)dibenzothiophene sulfone (
2DBSOSPO
), 3-(diphenylphosphoryl)dibenzothiophene sulfone (
3DBSOSPO
) and 4-(diphenylphosphoryl)dibenzothiophene sulfone (
4DBSOSPO
) were developed to support blue thermally activated delayed fluorescence (TADF) devices with high performance through optimizing intralayer and interlayer compatibility of emissive layers. On the basis of the triplet energy of ~3.0 eV for the hosts and ETMs, excitons can be effectively confined on
DMAC-DPS
. Compared to
DBTSPO
,
DBTDPO
can support the excellent distribution uniformity to blue TADF dye bis[4-(9,9-dimethyl–9,10-dihydroacridine) phenyl] sulfone (
DMAC-DPS
), owing to their configuration similarity; while
3DBSOSPO
and
4DBSOSPO
are superior in compatibility with the hosts due to the similar molecular polarity or configuration. Through adjusting the molecular configuration, the electrical performance of ETMs can be feasibly tuned, including the excellent electron mobility (μ
e
) by the order of 10
−3
cm
2
V
−1
s
−1
. As the result,
DBTDPO
and
4DBSOSPO
endowed their four-layer blue TADF devices with the maximum current efficiency of 33.5 cd A
−1
and the maximum external quantum efficiency more than 17%, which are impressive among the best blue TADF devices. It is showed that intralayer compatibility determines the maximum efficiencies, while interlayer compatibility influences efficiency stability. |
