摘要：When S- or R- oxazolylaniline enantiomers were
attached to achiral quinoline oligoamide foldamers (QOFs), a
single diastereomerically pure P- or M-handed foldamer was
observed and exhibits negative or positive circularly polarized
luminescence with the emission dissymmetry factors |glum| up to
0.038, which is significantly larger than that of QOF with
incomplete chiral induction. More importantly, the CPL
dissymmetry factors, together with the absorption dissymmetry
factors, are enhanced
