Tuning cation-binding selectivity and capacity via side chain-dependent molecular packing in the solid state

Abstract

Cavity-containing cation-binding pentameric macrocycles readily assemble, via side chain-dependent molecular packing, into either 1D nanotube bundles with the smallest being 10 nm in diameter or nanoplates of different sizes. The resultant nanostructures are able to selectively remove metal salts from aqueous solutions with varying selectivities and capacities.
