Clathrates, porphyrin sponges

Pursued applications of these clathrate porphyrin sponges include their use as materials to selectively immobilize and isolate molecular species and as intercalation compounds. The forces holding these solids... 

MgTPP has also been examined as a substrate for constructing porphyrin sponges, i.e., lattice clathrates that can reversibly absorb and release guest molecules. Such guests as methyl benzoate, propanol and (R)-phenethylamine) have been structurally authenticated other examples are known. " ...
