Article Synopsis
- - Two new cluster-based compounds with a one-dimensional belt-like structure were synthesized using solvothermal methods, featuring mixed-valence antimony (Sb(III,V)) in their compositions.
- - The structures are characterized by anionic clusters arranged in a sandwich formation, involving layers of specific chemical brackets and components related to cobalt and tartaric acid.
- - The second compound was found to have significant proton conductivity, reaching 1.42 × 10⁻² S/cm at 85 °C under high humidity conditions, demonstrating its potential for applications in conductive materials.

Two-dimensional carbon architectures are attracting tremendous interests for various promising applications due to their outstanding electronic and mechanical properties, although it is a great challenge to rationally devise facile and operative methodologies to engineer their structural traits owing to complex synthetic processes. Herein, for the first time, we fabricate two-dimensional carbon nanoribbons via direct thermal exfoliation of one-dimensional Ni-based metal-organic framework (MOF) nanorods, in which interconnected graphitic carbon nanocages are self-assembled into a belt-like superstructure with carbon-encapsulated Ni nanoparticles immobilized on the surface. Due to the unparalleled structural superiority, the MOF-derived carbon nanobelts exhibit excellent catalytic performances in electrocatalytic hydrogen evolution.

Peptides or peptide conjugates capable of assembling into one-dimensional (1D) nanostructures have been extensively investigated over the past two decades due to their implications in human diseases and also their interesting applications as biomaterials. While many of these filamentous assemblies contain a β-sheet-forming sequence as the key design element, their eventual morphology could assume a variety of shapes, such as fibrils, ribbons, belts, or cylinders. Deciphering the key factors that govern the stacking fashion of individual β-sheets will help understand the polymorphism of peptide assemblies and greatly benefit the development of functional materials from customized molecular design.

Bottom-up fabrication of self-assembled structures made of nanoparticles may lead to new materials, arrays and devices with great promise for myriad applications. Here a new class of metal-peptide scaffolds is reported: coordination polymer Ag(I)-DLL belt-like crystals, which enable the dual-template synthesis of more sophisticated nanoparticle superstructures. In these biorelated scaffolds, the self-assembly and recognition capacities of peptides and the selective reduction of Ag(I) ions to Ag are simultaneously exploited to control the growth and assembly of inorganic nanoparticles: first on their surfaces, and then inside the structures themselves.
