Homoconjugation-Enabled Kagome Bands in a Layer-Decoupled Two-Dimensional Conductive Triptycene-Based Metal–Organic Framework
Abstract
despite having a finite band gap, a large surface area, and a strongly anisotropic transport. Density functional theory calculations suggest that these properties arise from the preserved symmetry-protected Dirac cone trivial topology within the layer-stacked bulk structure, governed by radicals in the quartet-state linker. This study establishes a general design strategy in which linker geometry is leveraged to suppress interlayer coupling, enabling experimental realization of monolayer-like electronic structures in stacked 2D MOF and providing a robust experimental platform for low-dimensional 2D MOF electronics and kagome lattice-based topological studies.
