The paper overviews iron-containing polymers prepared by controlled "living" ring-opening metathesis polymerization (ROMP). Developments in the design and synthesis of this class of organometallic polymers are highlighted, pinpointing methodologies and newest trends in advanced applications of hybrid materials based on polymers functionalized with iron motifs.

In this work, we report the design, synthesis, and application of a hyper-crosslinked heterogeneous organometallic porous organic polymer (Pd@TP-DPPF) catalyst for the efficient and sustainable dicarbofunctionalization of internal alkynes via a facile three-component reaction. This strategy enables the highly trans-selective syntheses of tetrasubstituted olefins in excellent yields. The catalyst is constructed by integrating triptycene (TP) and 1,1'-bis(diphenylphosphino)ferrocene (DPPF) into a robust palladium-based porous framework, resulting in a unique heterogeneous system that efficiently mediates the coupling of internal alkynes with readily available iodoarenes and aryl/methyl boronic acids.

Mechanically interlocked molecules (MIMs) exhibit unique properties and functions arising from their structural entanglement, features of which are absent in their individual components. However, synthesizing topologically complex architectures, particularly those with topological chirality, remains a significant challenge due to the lack of general methods for controlled entanglement. Herein, we report the stereoselective synthesis of a 24-metal-center topologically chiral [6]catenane featuring 18 crossings ( link), representing one of the most intricate MIMs constructed to date.

Chiral nanostructures hold transformative potential across diverse fields, yet their assembly construction remains hindered by the high entropic barrier of dissymmetric building units. Inspired by biological structural dynamics, we construct two chiral copper-based hydrogen-bonded frameworks [D(L)-Cu-crystals] via hydrogen-bonded assembly using chiral metal-organic helical as the building unit. Single-crystal X-ray diffraction elucidates hierarchical chirality evolution from asymmetric coordinations to helical chains and framework packing.

This paper describes the fabrication of multifunctional electronic textiles (e-textiles) capable of simultaneous detection and uptake of hydrogen sulfide (HS). Hydrothermal templation of the bismuth-based framework (Bi(HHTP)) onto the textile installs a conductive coating from the molecular building blocks of 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) and bismuth acetate. Electronic textile (e-textile) surfaces achieve average Bi(HHTP) loadings of 8 ± 2 mg cm, corresponding to 20% ± 4% of the e-textile being Bi(HHTP) by mass, and demonstrate average resistivities of 1.

Formic acid (FA) is considered one of the most promising carriers of clean and safe dihydrogen. This study highlights the potential of using poly-(2,6-dimethyl-1,4-phenylene oxide) (PPO) as a support for AuNPs to produce H through formic acid dehydrogenation (FAD). The developed synthesis method allows for precise control over the gold content by completely encapsulating AuNPs (4-6 nm) within the PPO matrix, ensuring a uniform distribution of nanoparticles with an active cubic morphology.
