Lyotropic liquid crystalline phases from helical β-peptides as alignment media

Chem Commun (Camb). 2011 Jan 7;47(1):502-4. doi: 10.1039/c0cc02123g. Epub 2010 Oct 25.

Abstract

Lyotropic liquid crystalline (LLC) phases from helical β-peptides are proposed as novel water-based alignment media. In contrast to α-peptides, β-peptides form LLCs at very short chain lengths and at concentrations as low as 1 percent. Spectra obtained in these LLC phases are artefact-free and lead to RDCs of the desired size. First indications towards enantiodiscrimination are provided.
