Development of New Supramolecular Lyotropic Liquid Crystals and Their Application as Alignment Media for Organic Compounds

Abstract

Abstract Most alignment media for the residual dipolar coupling (RDC) based molecular structure determination of small organic compounds consist of rod‐like polymers dissolved in organic solvents or of swollen cross‐linked polymer gels. Thus far, the synthesis of polymer‐based alignment media has been a challenging process, which is often followed by a time‐consuming sample preparation. We herein propose the use of non‐polymeric alignment media based on benzenetricarboxamides (BTAs), which self‐assemble into rod‐like supramolecules. Our newly found supramolecular lyotropic liquid crystals (LLCs) are studied in terms of their LLC properties and their suitability as alignment media in NMR spectroscopy. Scalable enantiodifferentiating properties are introduced through a sergeant‐and‐soldier principle by blending achiral with chiral substituted BTAs.
