Summary: Platinum(II) complexes exhibit versatile chromic behavior due to their square planar geometry, which allows for intra- and intermolecular Pt...Pt interactions. These interactions, along with various functional groups and environmental factors, can modulate the electronic properties and transitions of the complexes, making them attractive candidates for chromic devices in memory, encryption, sensors, and optoelectronics.

Summary: Heterometallic extended metal atom chains (EMACs) with three types of metal were synthesized by forming unbridged metal-metal bonds based on the interactions between molecular orbitals. These chains form pentanuclear structures with high formation constants for Pt and Pd, while retaining their back-bones in solution. In the case of Cu, the original Cu(+2) atoms were reduced to Cu(+1) with an unprecedented coordination geometry. The reported synthesis provides a guideline for the synthesis of hetero-EMACs with different metal nuclei and species.

Summary: Dinuclear d(8) Pt(ii) complexes exhibit photophysical properties determined by the distance between the two Pt(ii) centres, showing either metal-to-ligand-(MLCT) or metal-metal-ligand-to-ligand charge transfer (MMLCT) transitions. The novel dinuclear complexes with 8-hydroxyquinoline as the bridging ligand possess similar photophysics to the mononuclear model chromophore. TD-DFT calculations confirm the mixed LC/MLCT nature of the lowest energy absorption and the limited quantum yields of the (LC)-L-3 photoluminescence for these complexes.

Summary: The synthesis and characterization of dinuclear ligand-to-ligand charge transfer complexes with platinum(ii) coordinated to tert-butyl-orthocatecholate donor and di-tert-butyl-2,2'-bipyridine acceptor were described. The complexes exhibited ligand-to-ligand charge transfer bands in the visible spectrum and showed intramolecular interaction between the platinum centres. The excited state lifetimes of these complexes were twofold longer than the mononuclear parent complex. The properties of these complexes were discussed and compared to similar complexes in the literature.

Summary: Red and near-infrared (NIR) phosphorescent double-decker dinuclear Pt(II) complexes were synthesized and characterized for their structural and spectroscopic properties. The complexes were found to exist as racemic mixtures with different intramolecular Pt-Pt distances controlled by the electronic characteristics of the C^N ligands. The Pt-Pt distances significantly influenced the band gap energies and corresponding emission wavelengths of the complexes, suggesting a method to finely tune the phosphorescence of these Pt(II) complexes.

Summary: A new tellurium and mercury containing macrocycle was synthesized via (2+2) condensation reaction and exhibited an unsymmetrical figure-of-eight conformation in the crystal structure. The resulting silver complexes showed intramolecular Hg...Ag and Te...Ag interactions as well as intermolecular Hg...Hg interactions, forming an extended 1D molecular chain in a non-linear manner. Solution studies using Hg-199 and Te-125 NMR spectroscopy, absorption, and emission spectroscopy further investigated the behavior of Hg...Ag and Te...Ag interactions. DFT calculations, AIM analysis, NCI, and NBO analysis supported the experimental findings and revealed the stronger intermolecular Hg...Hg interaction compared to the intramolecular Hg...Ag interactions.

Summary: In this study, newly obtained atomically precise phosphine-thiolate protected Au-11-SH and cationic Au-13-SH with a unique aromatic ligand (quinoline-2-thiol) were used to reveal the origin of luminescence in metal nanoclusters. By comparing with the traditional phosphine-halide-protected Au-11-Cl and Au-13-Cl, it was found that the conversion of chloride to thiol triggered room-temperature luminescence in Au-11 and modulated the luminescence behavior of Au-13. Ultrafast UV/IR spectroscopy and transient absorption spectroscopy provided insights into the relaxation process from ligand to core state, affecting the dynamics of excited states and intermediate states, leading to efficient room-temperature emission. The findings have implications in the fields of lighting, light harvesting, and photocatalysis.

Summary: The hydrogen evolution activity of PS-double-layered photocatalysts was studied in the presence of redox-reversible electron donors. The polyoxometalates acted as effective electron donors and the photocatalyst showed an apparent quantum yield of 0.39% in the initial hour. Energy transfer deactivation from photoexcited PS* to surface-immobilized polyoxometalates was identified as the reason for lower quantum yield.

Summary: To enhance solar-fuel production, a new heteroleptic Ru (II)-picolinate complex, Rupic, was synthesized as a red light-absorbing molecular photosensitizer. Rupic exhibited metal-to-ligand charge-transfer absorption and emission over a longer wavelength region than its bipyridine derivative, Rubpy. The Rupic-sensitized Pt-TiO2 nanoparticles showed significantly higher photocatalytic H2 evolution reaction activity under red light illumination compared to Rubpy-sensitized analog, indicating the superior photosensitizing performance of Rupic for H2 production under sunlight.

Summary: One-directional electron transport is crucial for efficient Z-scheme water-splitting photocatalysis. A photoredox cascade catalyst was synthesized to mimic natural photosynthesis's electron transport chain, using Pt-TiO2 nanoparticle catalyst, two photosensitizers (RuCP6 and RuP6), and a visible-light-transparent electron mediator (HCRu). The catalyst, named PRCC-1, exhibited the highest initial apparent quantum yield (iAQY = 2.23%) among dye-sensitized TiO2 photocatalysts, and successfully produced hydrogen using hydroquinone monosulfonate as the hydrogen source.

Summary: Molecular crystals of Pt(ii) complexes with metallophilic interactions can exhibit bright assembly-induced luminescence with colour tunability. However, their brittleness hinders their application in flexible optical materials. In this study, the elastic deformation of crystals of polyhalogenated Pt(ii) complexes was achieved, resulting in bright luminescence. The crystal of [Pt(bpic)(dFppy)] showed ligand-centred emission, while the co-crystal of [Pt(bpic)(dFppy)] and [Pt(bpic)(ppy)] exhibited metal-metal-to-ligand charge transfer emission with a significantly higher emission quantum yield.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
