Lieb lattice has been extensively studied to realize ferromagnetism due to its exotic flat band. However, its material realization has remained elusive; so far only artificial Lieb lattices have been made experimentally. Here, based on first-principles and tight-binding calculations, we discover that a recently synthesized two-dimensional sp<sup>2</sup> carbon-conjugated covalent-organic framework (sp<sup>2</sup>c-COF) represents a material realization of a Lieb-like lattice. The observed ferrom ...[more]
