摘要

Experimental evidence presented in this paper shows that long-range crystalline order as observed in the macrocyclic heteroditopic receptors’ single-crystal structures is preserved when embedded in the bilayer membranes. Investigations presented here showed that MCM_41-type mesoporous hydrophobic hybrids can be used as biomimetic platforms for ion-channel biomimetic structure elucidation, while showing similar hydrophobic interactions with confined ligands/receptors as in bilayer membranes. This gives access to information concerning the structural pictures of the bilayer’s confined ion-channel structures, as well as of their relatives in the presence of ion effectors.
