Imidazolium-Functionalized BINOL as a Multifunctional Receptor for Chromogenic and Chiral Anion Recognition Qiao-Sen Lu Liang Dong Ji Zhang Jing Li Lu Jiang Yu Huang Song Qin Chang-Wei Hu Xiao-Qi Yu 10.1021/ol8027303.s001 https://acs.figshare.com/articles/journal_contribution/Imidazolium_Functionalized_BINOL_as_a_Multifunctional_Receptor_for_Chromogenic_and_Chiral_Anion_Recognition/2880847 A novel imidazolium-functionalized BINOL fluorescent receptor <b>R-1</b> was developed as a multifunctional receptor for both chromogenic and chiral anion recognition. The different fluorescent responses and color changes of <b>R-1</b> could be applied to the detection of fluoride and acetate ions by the naked eye. Furthermore, the chiral recognition of the two enantiomers of α-amino carboxylates was also studied, and <b>R-1</b> displayed a remarkable binding ability for the <i>t</i>-Boc alanine anion with an interesting enantioselectivity (<i>K</i><sub>L</sub>/<i>K</i><sub>D</sub> = 4.5). 2009-02-05 00:00:00 enantioselectivity alanine receptor R binding ability Chiral Anion Recognition detection Chromogenic chiral anion recognition enantiomer carboxylate multifunctional receptor color changes chromogenic BINOL chiral recognition response Multifunctional Receptor acetate ions KL fluoride
