The emergence, transference, amplification, and memory of chiroptical activity in supramol. assemblies, including circularly polarized absorbance and circularly polarized luminescence, remain significant challenges. Herein, an achiral pyridine-substituted coumarin derivative and chiral additives can coassemble into helical nanostructures with fine chiroptical activity via subtle hydrogen-bonding interactions. The resulting supramol. assemblies remain optically active even after the removal of chiral additives, demonstrating supramol. chirality can be remembered in the assemblies. More importantly, the removed chiral elements can be reused to achieve continuous circulation and amplification of chirality. This work presents insight into the emergence, transference, amplification, and memory of chirality in a supramol. assembly system and could be applied to the manufacturing of chiroptical materials. In addition to this study using Picolinic acid, there are many other studies that have used Picolinic acid(cas: 98-98-6Quality Control of Picolinic acid) was used in this study.
Picolinic acid(cas: 98-98-6) is used as a chelate for alkaline earth metals. Used to prepare picolinato ligated transition metal complexes. In synthetic organic chemistry, has been used as a substrate in the Mitsunobu reaction and in the Hammick reaction.Quality Control of Picolinic acid
