  • Title: Helical Polyisocyanopeptides as Lyotropic Liquid Crystals for Measuring Residual Dipolar Couplings.
    Author: Li GW, Cao JM, Zong W, Hu L, Hu ML, Lei X, Sun H, Tan RX.
    Journal: Chemistry; 2017 Jun 07; 23(32):7653-7656. PubMed ID: 28382647.
    Abstract:
    Residual dipolar couplings (RDC) emerged to be an important structural parameter for organic and biomolecules. Herein, a new helical polyisocyanopeptide (l,l-PIAF-OBn) that forms lyotropic liquid crystals (LLC) in CDCl3 is proposed as a novel weakly orienting medium for acquiring residual dipolar couplings (RDCs) of organic molecules. We demonstrate its application for the structural elucidation of strychnine and triptolide.
