Patent ID: 8871186

Claim:
A composition that spontaneously forms a supramolecular mixed host clathrate that entraps desired guest moieties, which composition comprises at least first and second components that are different from each other, are hydrophilic and are spontaneously self-assembling to form an asymmetric intercalated lattice framework, wherein when contacted with potential guest moieties said composition forms nanocages that are conformationally mimetic and antisymmetric to said guest moieties, wherein said first component has a surface area of at least 380 m 2 /g and >8 functional reactive hydrogen-bonding groups per nm 2 , and wherein the second component has a surface area of at least 425 m 2 /g; and wherein the first component is reactive fumed silica and the second component is a synthetic or natural zeolite Y, faujasite or mordenite.
