In an article, author is Shen, Wei, once mentioned the application of 6969-71-7, HPLC of Formula: C6H5N3O, Name is [1,2,4]Triazolo[4,3-a]pyridin-3(2H)-one, molecular formula is C6H5N3O, molecular weight is 135.12, MDL number is MFCD00022632, category is pyridine-derivatives. Now introduce a scientific discovery about this category.
A donor-acceptor ligand boosting the performance of FA(0.8)Cs(0.2)PbBr(3) nanocrystal light-emitting diodes
A donor-acceptor ligand, 3-amino-2-bromo-6-methoxypyridine (ABMeoPy), was introduced to passivate FA(0.8)Cs(0.2)PbBr(3) nanocrystals (NCs) by a post-processing method. The donor-acceptor interaction can greatly enhance the coordination bond of pyridine-Pb2+, and improve FA(0.8)Cs(0.2)PbBr(3) NC performance with 95.99% photoluminescence quantum yield (PLQY), 6-month stability in solution, and 26% trap density decrease. In the light of ABMeoPy passivation of FA(0.8)Cs(0.2)PbBr(3) NCs, the maximum luminance, the maximum current efficiency, and EQE of light-emitting diodes (LEDs) increased 69%, 110%, and 111%, respectively. The strategy of using D-A molecules to passivate perovskite NCs is quite simple and effective, which can be widely promoted in perovskite-based LEDs or solar cells.
