A novel terpyridine-based, trapezoidal architecture was synthesized by a coordination-driven multicomponent assembly and features three different tpy-M-tpy bonds (M = Ru, Fe, and Zn) in the macrocyclic ring. This trimetallic macrocycle introduces the construction of polymetallosupramolecular assemblies possessing multiple, differing metal centers in an ordered, predetermined pattern. Characterization was accomplished by NMR spectroscopy, mass spectrometry, and UV-Vis spectroscopy.

Proton exchange membrane fuel cells (PEMFCs) are being pursued for applications in the maritime industry to meet stringent ship emissions regulations. Further basic research is needed to improve the performance of PEMFCs in marine environments. Assembly stress compresses the gas diffusion layer (GDL) beneath the ribs, significantly altering its pore structure and internal transport properties.

Polynuclear Au(I) cluster photocatalysts, known for their high activity and stability, hold substantial potential in organic synthetic chemistry. This study synthesized two Au(I) supramolecular cluster catalysts with different nuclearities: a tetranuclear cluster, C1 ([(dppmAu2)2L1]•PF6-), and a hexadecanuclear cluster, C2 [(dppmAu2)6(Au4)(L1)4]•4PF6-, through a multicomponent stepwise self-assembly approach. Both cluster structures feature aurophilicity interaction motifs that endow them with exceptional photocatalytic performance, exhibiting optical band gaps of 2.

Micron-scale colloidal particles with short-ranged attractions, e.g., colloids functionalized with single-stranded DNA oligomers, have emerged as a powerful platform for studying colloidal self-assembly phenomena with the long-term goal of identifying routes for metamaterial fabrication.

Controlled high-order clustering of cell-surface proteins is an essential but unmatched regulatory mechanism in living systems for the modulation of cell behavior. Here, we present a strategy for generating extended and tunable one-dimensional clusters of death receptors on live cell surfaces by employing synthetic peptides to noncovalently bridging the proteins. The on-cell assembly process is validated through super-resolution fluorescence imaging and fluorescence lifetime imaging analyses.

The judicious selection and combination of multicomponents provide great potential for the further exploration of new polyoxometalate (POM) materials. Here, a delicate control on tungstate, Sb and Bi sources, Eu ions, and organic molecules led to the discovery of a novel multimetal cluster-embedded POM [HN(CH)]NaH{[Eu(HO)SbBiWO](SbWO)(SbWO)}·78HO (). The polyoxoanion of was constructed from four in situ-formed [SbWO] and [SbWO] building blocks connected by two hexa-metallic [Eu(HO)SbBiWO] clusters, to be a rare member of Sb- and Bi-coexisting POM.
