Due to their fascinating topological structures and application prospects, coordination supramolecular complexes have continuously been studied by scientists. However, the controlled construction property study of organometallic handcuffs remains a significant challenging research subject in area chemistry. Hence, series tetranuclear heterometallic bearing different size metal types were rationally designed successfully synthesized utilizing quadridentate pyridyl ligand (tetra-(3-pyridylphenyl)ethylene) based on three Cp*Rh (Cp* = η5-C5Me5) fragments specific longitudinal dimensions conjugated planes. These results determined with single-crystal X-ray diffraction analysis technology, ESI-MS NMR spectroscopy, etc. Importantly, photoquenching effect Cp* groups discrepancy intermolecular π-π stacking interactions between building block half-sandwich promote markedly photothermal conversion results. will further push synthesis development materials.

By exploiting coordination-driven self-assembly, high yields of two 818 molecular metalla-knots could be obtained using a thiazole-moiety-containing asymmetric dipyridyl ligand 2-(pyridin-4-yl)-5-(pyridin-4-ylethynyl)benzo[d]thiazole (L1 ), as confirmed X-ray crystallographic analysis, electrospray ionization-time-of-flight/mass spectrometry (ESI-TOF/MS), and detailed liquid-state nuclear magnetic resonance (NMR) spectroscopy. To modulate the self-assembled structures, m-chloroperbenzoic acid (m-CPBA) was utilized to oxidize thiazole-based L1 N-thiazole-oxide-based 3-oxide (L2 which enabled selective construction corresponding tetranuclear macrocycles. Notably, topologically transformed from knots simple monocycles because alkyne bond inert toward m-CPBA, by NMR spectroscopy, ESI-TOF/MS, elemental analysis.

Comprehensive Summary Research into controlling the self‐assembly of discrete porous organic cages (POCs) with specific geometries and functions is difficult, but important for understanding their structure‐property relationship, as well behavior in supramolecular chemistry. Herein, we report two POCs based on same tetraformyl‐functionalized calix[4]resorcinarene (C4RACHO) 2,4‐diaminophenol dihydrochloride (DAP) building blocks, including a [3+6] triangular prism ( CPOC‐201‐OH ) [4+8] square CPOC‐401‐OH ), determined by single X‐ray crystallographic analysis. Both exhibit large intrinsic cavities, rich oxygen sites, high porosity Brunauer–Emmett–Teller (BET) surface areas up to 966 m 2 ·g –1 . Owing such virtues, both can effectively capture iodine aqueous media removal rate > 99% within min.

Furthermore, given the inherent compactness of metalla‐knots, it creates favorable conditions for emergence steric repulsion. We focused on progressively introducing nitrogen atoms featuring lone pair electrons (LPEs) into manipulate balance H⋅⋅⋅H/LPEs⋅⋅⋅LPEs repulsion during assembly process, ultimately achieving controlled from pseudo ‐Solomon link and then molecular tweezer‐like facilitated by stacking interactions. All assemblies were well characterized solution‐state NMR techniques, ESI‐TOF/MS, single‐crystal X‐ray diffraction. The evolutionary process topological architectures is equivalent visualizing synergistic effect hindrance interactions structural assembly, providing new avenue synthesis different topologies.
