PO-T2T是有机发光二极管(OLED)中的电子传输/空穴阻挡材料，或有机电子器件中的电子受体材料。

一项在《自然》发表的研究演示了自由基OLED的有效作用，它们通过自旋双线态激子发光，而不是单线态和三线态激子。
双线态激子没有跃迁过程中的自旋禁阻问题，从而避开了长久以来的三线态激子的利用问题。采用发光自由基激子的OLED，最大外量子效率已达到27%（710nm），是目前为止已报道的深红光/近红外光发光二极管(LED)中的最高值。在这种高效的OLED器件中，采用TAPC作为空穴传输层，PO-T2T作为电子传输层，实现选择性地空穴注入HOMO，电子注入SOMO，形成近100%内量子效率的荧光双线激发态。
装置配置:
ITO/MoO3 (3 nm)/ TAPC (35 nm)/CBP:TTM-3NCz (3.0 wt%; (40 nm)与CBP:TTM3PCz (3.0 wt%; 25 nm)/B3PYMPM (10 nm)/PO-T2T (70 nm)/LiF (0.8 nm)/Al (100 nm)。

首个基于激基复合物的串联白光有机发光二极管(WOLED)使用PO-T2T材料，设置mCP/PO-T2T和DTAF/PO-T2T两个平行混合层(parallel blend layer)，分别产生蓝色和黄色的激基复合物发光。制成的器件成为首个效率优异的基于激基复合物的串联WOLED ηext：11.6%，ηc：27.7 cd/A，和ηp：15.8 ml/W，CIE(0.29, 0.35)和CRI 70.6，几乎不依赖于电致发光(EL)强度。串联构造和混合层供体/受体(1:1)配置是WOLED制造的两个要点，充分利用了激基复合物的延迟荧光，是使用丰富的低成本有机物制造商业化WOLED的典范。

Organic light-emitting diodes (OLEDs)1-5, quantum-dot-based LEDs6-10, perovskite-based LEDs11-13 and micro-LEDs14,15 have been championed to fabricate lightweight and flexible units for next-generation displays and active lighting. Although there are already some high-end commercial products based on OLEDs, costs must decrease whilst maintaining high
