Abstract :

The four novel derivatives of 1,1'-bi-2-naphihol (BINOL) have been prepared, and the structures of these compounds have been characterized by IR, MS, [sup.1]H and [sup.13]C NMR spectroscopy, and elemental analysis. The enantioselective recognition of these receptors has been studied by fluorescence titration and [sup.1]H NMR spectroscopy. The receptors exhibited different chiral-recognition abilities towards some enantiomers of chiral materials and formed 1:1 complexes between host and guest. The receptors exhibit excellent enantioselective fluorescent-recognition ability towards the amino acid derivatives. Key words: receptor, fluorescence, enantioselective recognition, anions, NMR spectroscopy. On a prepare quatre nouveaux derives du BINOL et on en a determine les structures par analyse elementaire et par s pee tros copies infrarouge, de masse et RMN du [sup.1]H et du [sup.l3]C. On a etudie les proprietes de reconnaissance enantioselective de ces recepteurs par titrage de fluorescente et par spectroscopie RMN du [sup.1]H. Les recepteurs presentent diverses capacites a reconnaitre la chiralite de quelques enantiomeres de produits chiraux et ils forment des complexes 1:1 entre molecules hotes el invitees. Les recepteurs presentent une capacite excedente de reconnaitre une fluorescence enantioselective vis-a-vis des derives d'acides amines. Mots-cles: recepteur, fluorescence, reconnaissance enantioselective, anions, spectroscopie RMN. [Traduit par la Redaction]
