Conformation of oligocholate foldamers with 4-aminobutyroyl spacers

The studies related to the observed fluorescence resonance energy transfer (FRET) from the naphthyl to the dansyl in 2:1 hexane/ethyl acetate (EA) containing a few percent of methanol are reported. The results showed that the conformation of the oligocholates is strongly influenced by the 4-aminobutyroyl spacers.
