Web(1) Substitutions greatly increase solubility of substituted Q [ n ]s by decreasing solid-state packing. (2) Unsymmetrical substitutions deform the cavity symmetry and open up better selectivity to guest sequestration. 39,40,50,56 It should be noted that Q [ n ]s are amongst some of the most selective hosts because of their different cavity sizes.
