In a recent article published in Nature Chemistry, an international research team reports an anisotropic reticular chemistry (ARC) strategy for constructing two-dimensional conjugated metal–organic frameworks (2D c-MOFs) with programmable topologies and spatially defined metal nodes from a single molecular building block. By exploiting chemically inequivalent coordination sites within a low-symmetry ligand, ARC enables atomic-level control over framework assembly and provides a general route to tuning the electronic structure and charge transport of organic 2D Crystal materials. more

In a recent study published in Nature, an international team of researchers reports, for the first time, lattice-defined 2D vdW heterostructures for organic 2D crystals at near-zero twist. On-water surface synthesis enables sequential assembly of chemically distinct 2D polymers to be stacked with defined lattice registry, while introducing a new lattice-control knob through programmable lattice matching and mismatching from 0% to 18%. Lattice-matched 2D vdW heterostructures exhibit commensurate epitaxy and chemically sharp interfaces, whereas large lattice mismatch gives rise to moiré features and strain-relief distortions. The precisely defined interfaces further enable designed interfacial electronic coupling, band alignment and dipole formation, together with record vertical current rectification controlled by lattice registry, reaching rectification ratios above 10⁷. more

In a recent article published in Nature Communications, researchers from Technische Universität Dresden, the Max Planck Institute for Polymer Research, the Max Planck Institute of Microstructure Physics, Beijing Institute of Technology, and collaborating institutions report a pyridine-coordinated two-dimensional polymer crystal that combines efficient free-carrier generation with band-like transport. By bridging adjacent Cu–porphyrin layers with pyridine, the team suppresses exciton binding below room-temperature thermal energy, enabling charge mobilities approaching 500 cm² V⁻¹ s⁻¹ and a photon-to-free-carrier conversion ratio of approximately 0.4. more

Researchers have developed a proton-switchable two-dimensional polymer that adapts its interaction with iodine species during battery operation. The approach suppresses polyiodide shuttling without slowing redox reactions, enabling zinc–iodine batteries to run for 51,000 cycles at 25 °C and more than 70,000 cycles at −20 °C, while retaining excellent performance at high iodine loading. more
