Atropisomerism in a polyglutamate-based thermoresponsive alignment medium†
Structure elucidation via residual dipolar couplings (RDCs) relies on alignment media. We report on lyotropic liquid crystals (LLCs) of poly-γ-p-biphenyl(2′-methoxy-2-methyl)methyl-L-glutamate (PBPM3LG). Temperature dependent atropisomerism within the biphenyl group enables the acquisition of multiple RDC-datasets within one sample.
