摘要:Herein are disclosed fluorescent dyes based around a framework for a ligand comprising a pyridyl group linked to a diaryl anilido unit. A variety of ligands based on this framework are disclosed. The ligands chelate to a BF 2 center to produce the fluorescent dye. The disclosed dyes combine longer Stokes shifts (approximately 100 nm) with increased quantum yields. They are also photostable in aqueous and organic solutions for several hours. These dyes may be used in the labeling of biomolecules for bioimaging and assays. Also disclosed are methods for the synthesis of these dyes.

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.
