Novel Chiral Molecular Tweezer from (+)-Usnic Acid

A new chiral molecular tweezer was synthesized with (1<i>R</i>,2<i>R</i>)-1,2-diaminocyclohexane as spacer and two molecules of (+)-usnic acid as pincers. The ability of this molecular tweezer to bind 2,4,7-trinitrofluorenone was studied. A charge-transfer complex was formed in which TNF was sandwiched between the two usnic acid units with π−π-stacked aromatic interactions.
