摘要:以蒽生色团为核心基团和苯基咔唑生色团为侧基,合成了三种新的蓝光发射体2-Dcpa,3-Dcpa和4-Dcpa.三种化合物在咔唑与核连接的位置方面有所不同,使用咔唑节点的2-Dcpa和4-Dcpa和使用波瓣位置的3-Dcpa.进行密度泛函理论计算以确定咔唑部分的哪些位置具有结点特征以及哪些具有叶特征.最大pl薄膜状态下的2-Dcpa,3-Dcpa和4-Dcpa的值分别在蓝色区域,分别在453,457和452 Nm处.在这些材料中,3-Dcpa(即与波瓣位置链接的材料)显示出最高的效率,值为2.91 Cd / A,而eqe的显示为2.65%.在使用cbp作为主体材料并使用3-Dcpa作为掺杂剂的掺杂器件中,观测到el最大发射在深蓝色区域中,在433 Nm处,并且cie值为(0.150,0.068).

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.
