Macrocyclic module compositions are made from cyclic synthons. The macrocyclic module structures are prepared by stepwise or concerted schemes which couple synthons in a closed ring. The macrocyclic module structures may have a pore of nanometer dimensions.

The invention relates to the use of compositions derived from metal-accumulating plants, wherein the metals are more particularly zinc, nickel and copper, for implementing chemical reactions especially catalytical reactions, a method for the preparation of specific Ni-containing composition, and said Ni-containing composition.
Nanofilms useful for filtration are prepared from oriented amphiphilic molecules and oriented macrocyclic modules. The amphiphilic species may be oriented on an interface or surface. The nanofilm may be prepared by depositing or attaching an oriented layer to a substrate. A nanofilm may also be prepared by coupling the oriented macrocyclic modules to provide a membrane.
