Cross-linked helically chiral poly-(γ-benzyl-L-glutamate) as enantiodiscriminating alignment medium.

The best of both worlds: By crosslinking poly-(γ-benzyl-L-glutamate) (PBLG), an alignment medium, which combines the scalability of cross-linked polymer gels (strain-induced-alignment media) with the enantiodiscriminating properties of helically chiral PBLG, was obtained. Spectra of excellent quality and residual dipolar couplings (RDCs) of the perfect size can be obtained for small organic compounds (see scheme; Bn = benzyl).
