| Popis: | In order to estimate oxygen permselectivities through a supramolecular polymer membrane for the first time , we prepared three kinds of composite membranes consisting of a supramolecular polymer membrane and a conventional organic polymer membrane. Supramolecular polymer membranes were prepared by using highly selective photocyclic aromatization of poly(substituted acetylene)s. It was found that the supramolecular polymer membrane had oxygen permselectivity (α = P O 2 / P N 2 ) around three in spite of its low molecular weight. |
