Formation stages of perfectly oriented nanosheets, out of building blocks of (1,3,5-tris-(4-carboxyphenyl)-benzene), with long-range molecular columns, and size- and position-regulated nanopores on an aqueous surface (a–c); (d) typical GID profile with $q_{xy}=\sqrt{q_x^2+q_y^2}$; and (e) reconstructed structure of the 2D crystal.
