Abstract

Abstract : We report on the design and synthesis of new enantiopure binaphthyl derivatives in which electron-donating and electron-withdrawing substituents are placed in direct conjugation, to create push-pull dyes potentially active for NLO applications. The dyes, unprecedentedly, extend their π -bridge from the 3, 3′ positions of the binaphthyl units and incorporate as acceptors 1, 3-dicarbonyl and tetrafluorobenzene units, useful for further supramolecular polarization of the chiral dyes.
