Lyotropic liquid crystal to measure residual dipolar couplings in dimethyl sulfoxide based on modified cellulose nanocrystals†
Abstract
A novel lyotropic liquid crystal (LCC) was developed by grafting polymer brushes onto cellulose nanocrystals (CNCs) via free radical polymerization. It shows alignment properties to measure residual dipolar couplings (RDCs) of small organic molecules in DMSO without interference from background NMR signals of the polymer.
