Abstract
A molecular sieve that has high selectivity and enables high-speed molecular permeation is provided. The molecular sieve has a nanowindow formed lacking a portion of carbon atoms in graphene, and one or more heteroatoms substituting for one or more carbon atoms that constitute a rim of this nanowindow, in which an electrostatic field is induced within the nanowindow by the heteroatoms, the rim of the nanowindow is relaxed in cooperation with a permeating molecule having a van der Waals' radius larger than the nanowindow, and the molecular sieve becomes permeable to the permeating molecule.
