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.

Abstract Inorganic single‐walled nanotubes (SWNTs) play an important role in various fields because of their unique physical and chemical properties. A variety inorganic SWNTs have been synthesized, formation mechanisms well studied, which are mainly divided into two parts: through layered structures non‐layered structures. Among them, the exploration traditional boron nitride transition metal disulfide compounds is a little difficult, large number high‐temperature gas‐phase reactions still dominated by products multi‐wall nanotubes. In contrast, high‐quality pure monodisperse can be produced under simpler milder conditions solution phase. This review focuses on synthesis, mechanism, application these nanotubes, used to encapsulate or support nanoparticles single atoms prepare high‐performance catalysts. provide new viewpoints design applications SWNTs.

Abstract Understanding the complexity of nanostructures involved during supramolecular polymerization process can be achieved by kinetic control rather than thermodynamic stability. Study on pathway and associated will provide precise over materials' properties. This work illustrates structural transformation a naphthalimide‐(NMI)‐conjugated dipeptide from monomer to thermodynamically stable aggregated state in binary mixed solvent system (DMSO water). The self‐assembly propensity modulated changing ratio water, which offers an effective approach stability on‐pathway gel before reaching its crystalline precipitate state. An in‐depth spectroscopic microscopic investigation suggested that initiated formation tiny particles, further nucleated form helical nanofibrilar assembly. At higher water percentages, showed transient behavior proceeded toward However, at lower percentage, is kinetically trapped Here, helicity nanofibers altering percentage solvent. self‐assembled completely thermoreversible retain chiral memory even after complete dissolution respective composition.

The building block Pyra-Chol has been designed and synthesized, which exhibits different achiral morphologies in good solvents, forming nanospheres THF nanoflowers 1,4-dioxane. In the presence of water as a poor cosolvent, demonstrates an agnostic behavior, generating left-handed superhelices water:THF (80:20) solvent system. However, when is switched to 1,4-dioxane, change chirality observed water:1,4-dioxane (30:70) system, resulting formation fused nanospheres. Interestingly, cosolvent changed from MCH THF, chiral pattern remains unchanged, but morphology changes completely. Supported by collective spectroscopic microscopic analysis, present study efficaciously remarkable control hydrophobic over sense also highlights fascinating influence well supporting distinct molecular packing.
