为了产生高效的深蓝色发射器，设计了基于二苯并稠合磷酸环的新热激活延迟荧光（TADF）分子家族。采用苯硫膦硫化物衍生物作为TADF发射体的OLED显示出蓝色电致发光，最大外量子效率为13%，CIE色坐标为(0.15，0.23)。
To produce efficient deep-blue emitters, a new family of thermally activated delayed fluorescence (TADF) molecules based on dibenzo-fused phosphacycles was designed. OLEDs employing a phenothiaphosphine sulfide derivative as a TADF emitter displayed blue electroluminescence with a maximum external quantum efficiency of 13% and CIE color coordinates of (0.15, 0.23).
