Assembly–disassembly switching of self-sorted nanotubules forming dynamic 2-D porous heterostructure

Abstract

We report the pH-driven formation of a dynamic 2-D porous heterostructure through assembly–disassembly switching of the stacked macrocycles of nanotubules and their subsequent spreading on the surfaces of a self-sorted sheet assembly in a hierarchical co-assembly. The 2-D ordered porous heterostructure is able to discriminate spherical C₆₀ from flat coronene through shape selective adsorption.
