Engineering of flat bands and Dirac bands in two-dimensional covalent organic frameworks (COFs): relationships among molecular orbital symmetry, lattice symmetry, and electronic-structure characteristics

Abstract

An effective framework for the band engineering in 2D covalent organic frameworks is revealed by describing the fundamental relationships among the electronic structures, the lattice symmetries, and the frontier molecular orbitals of building units.
