Highly concentrated single-chain atomic crystal LiMo3Se3 solution using ion-exchange chromatography

Abstract

Ion-exchange chromatography can be used to effectively replace the lithium ion of LiMo₃Se₃ with a proton. The enlargement of the Stern layer distance caused by this ion exchange improves the dispersibility of (Mo₃Se₃⁻)_∞ chains and also prevents the re-bundling and aggregation of nanowires in aqueous solutions, even at high concentrations (1 mg mL⁻¹).
