Graphdiyne nanoribbons with high chemical precision are of great significance for further understanding of the intrinsic properties of graphdiyne and the relationship between structure and properties. However, the reliable synthesis of graphdiyne nanoribbons with chemical precision remains a significant challenge. A facile method is now presented for fabrication of graphdiyne nanoribbons with uniform width through stepwise inter‐ and intramolecular Glaser–Hay coupling reaction of ethynyl groups. The synthetic ribbons were interwoven into nanotextiles by π–π stacking and were applied for protective coating of Li‐electrode in Li‐ion batteries, which efficiently suppressed the growth of the Li dendrites during cycling and prolonged the life span of Li‐metal batteries.

The synthesis of graphdiyne with an ordered internal structure is highly attractive for its various scientific and application investigations. We reported herein a rational method to fabricate a graphdiyne analogue with the help of supramolecular chemistry. The introduction of π−π/CH−π interactions controlled the conformations of the precursors and afforded multilayer graphdiyne analogue Ben-GDY through the wet chemical method. The in-plane periodicity of the multilayer Ben-GDY was corroborated by transmission electron microscopy and selected area electron diffraction, which showed a pattern well matched with ABC-style stacking.

A helical fiber-like structure from a three dimensional arrangement of an alkyne exhibits good ability for photocatalytic hydrogen generation using a Pt co-catalyst.

Three new metal-organic frameworks based on flexible ligands (FL-MOFs) generally formulated as[H 2 chdc = 1,4-cyclohexanedicarboxylic acid, bpe = 1,2-bis(4-pyridyl)ethane and bpp = 1,3-bis(4pyridyl)propane], have been hydrothermally synthesized and characterized. The crystal structures of the three compounds feature one-dimensional infinite chains cross-linked via flexible ligand skeletons to form three-dimensional networks. Of peculiar interest, compound 1 represents a rare self-catenated MOF with a 6 5 •8-zst topology, which shows high sensitivity and quick response to the presence of trace amounts of nitroaromatic compounds. Meanwhile, the excellent ability of 1 for selective detection of 4-nitrotoluene in the presence of other nitroaromatic compounds has been demonstrated. The recyclability and reusability of 1 have also been tested based on consecutive detection reactions, in which 1 remains unchanged and detection efficiency is maintained.
