Subnanometer materials (SNMs) refer to nanomaterials with a feature size close 1 nm, similar the diameter of single polymer, DNA strand, and cluster/unit cell. The growth assembly subnanometer building blocks can be controlled by interactions at atomic levels, representing limit for precise manipulation materials. size, geometry, flexibility 1D SNMs inorganic backbones are polymer chains, bringing excellent gelability, adhesiveness, processability different from nanocrystals. ultrahigh surface atom ratio results in significantly increased energy, leading significant rearrangement atoms. Unconventional phases, immiscible metal alloys, high entropy few layers stabilized, spontaneous twisting may induce intrinsic structural chirality. Electron delocalization also emerge subnanoscale, giving rise enhanced catalytic activity. In this perspective, we summarized recent progress on SNMs, including their synthesis, polymer-like properties, metastable chirality, toward energy conversion. As critical region nanoscience, development functional fuse boundary polymers conduce manufacturing levels.
