摘要:固溶处理的有机发光二极管(oled)由于其简单的制造过程和易于扩展的固溶过程而备受关注.在这项工作中,设计并合成了可热交联的热活化延迟荧光(tadf)分子dv-Moc-Dps.此外,还合成了具有高三重态能量的可热交联的主体材料dv-Cdbp.通过结合两个可交联的乙烯基苄基醚基团,这两种具有出色热稳定性的材料可以在180oc加热后完全交联.另外,Dv-Cdbp和dv-Moc-Dps的质量比不同的交联膜研究了(1∶0.06,1∶0.09和1∶0.12).交联的膜非常光滑,均方根(rms)粗糙度在0.622 Nm至0.725 Nm的范围内.同时,质量比为1∶0.09的交联膜表现出0.71的最高光致发光量子产率.通过将交联膜用作发射层,获得了有效的蓝色溶液处理的oled,其最大外部量子效率为2.0%.本文报道的分子设计为高效溶液加工的oled提供了一条新颖的途径.

摘要:The present disclosure describes the synthesis, characterization, and purification of functionalized aromatic phosphonic acids (FAPAs) for use as hole extraction materials in perovskite solar cells and display devices. Embodiments of the present disclosure provide a method to prepare FAPAs with varying dipoles that can significantly improve the electronic properties of electrode materials used in displays and photovoltaic devices. The FAPA may be tuned for specific active layers. Aspects of the disclosure include phosphonic acid molecules that enhance bonding at the perovskite/substrate interface to create a strong hole extraction polymer retaining high efficiency and improving ultraviolet stability of perovskite solar cells by suppressing ion migration at the embedded interface.
