Summary: A new method was developed to grow thick, conformal CdS shells that preserve the optical properties of 5 nm HgSe cores, with the doping of the core/shell particles quantitatively tuned through a simple postsynthetic Cd treatment. The CdS shell greatly increases the intraband emission intensity and raises important questions about the fundamental limits to achievable slow intraband relaxation in quantum dots.

Summary: Surface chemical regulation strategy can enhance the chemiluminescence (CL) performance of carbon nanodots (CDs), with optimized CD showing higher brightness and quantum yield compared to the initial CDs. This improvement is attributed to the decreased electron capture from water molecules generated during the CL process.

Summary: Treatment with metal halides can improve the emission brightness and optical properties of colloidal 2D PbSe nanoplatelets. Surface passivation leads to a significant increase in photoluminescence quantum yield and a decrease in full width at half-maximum. This has important implications for the application of 2D PbSe NPLs in fiber optics.

Summary: This article synthesized and characterized a series of Zn(II) complexes with a hydrazone ligand through single crystal X-ray diffraction, FT-IR, elemental analyses, and ESI-MS. X-ray crystallography confirmed the neutral or monoanionic form of the ligand upon coordination. The complexes were found to be mononuclear with tetra/penta/hexacoordinated zinc atoms. The supramolecular architectures of the complexes were significantly influenced by the counter anions. In addition, the complexes were investigated for their DFT, luminescence properties, antibacterial, and herbicide activities.

Summary: In this study, a charge donor/acceptor pair was designed to construct a light-harvesting system based on two chiral gold(I)-isocyanide complexes. By doping nonemissive S-AuI into blue-emitting S-AuCN, a tunable emission from blue to red was achieved. This large red-shifted emission was realized through the change in electronic properties and the resulting energy-transfer process between the S-AuCN dimer and red-emitting (S-AuCN)-(S-AuI) CT pair. Importantly, the energy-transfer process can be controlled by external stimuli, leading to high-contrast CPL switching properties. This study opens a new avenue for developing CPL switches using chiral organometallic complexes.

Summary: Modern photodynamic therapy relies on the interaction between photosensitizer and oxygen to produce singlet oxygen. Energy transfer from the triplet excited state of photosensitizer to the excited state of oxygen is well-established, while the transfer from the singlet excited state is believed to be insignificant. However, our study provides evidence of energy transfer between the singlet excited state and oxygen in the production of singlet oxygen. This finding has been verified through fluorescence intensity measurements and ultrafast pump probe experiments.

Summary: The physicochemical properties and catalytic performance of transition metals are highly dependent on their crystal phases. In this study, MoOx-modified Ru with different crystal phases (fcc and hcp) were investigated for the hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR). It was found that MoOx-Ru fcc exhibited superior catalytic activity and durability compared to MoOx-Ru hcp. This enhancement in performance was attributed to the optimal adsorption of H and OH on fcc Ru. This work emphasizes the importance of phase engineering in developing superior electrocatalysts.

Summary: In this paper, a series of Zn-TfOH/AC catalysts were synthesized using a simple impregnation method, and the Zn-1.5TfOH/AC catalyst showed optimal catalytic performance in the acetylene hydration reaction. The TfOH ligands effectively inhibited carbon accumulation and Zinc loss, improved acidic sites and the dispersion of active metal. The hydration reaction mechanism of Zn-TfOH/AC catalyst was explored, and it was found that the OH- in TfO-ZnOH participated in the reaction and was regenerated by the dissociation of H2O, lowering the energy barrier.

Summary: This study systematically explores the chain structure and mechanical properties of metallo-supramolecular polymers using a loop protected architecture. The mechanical stability of individual chains was found to be dependent on the strength of the bonds, with values three times higher than those measured using old methods. The unique loop protected structure reduces interference from non-specific interactions. Additionally, the single chain flexibility of metallo-supramolecular polymers was found to be comparable to covalent analogues.

Summary: The pursuit of good photophysical properties in organic optoelectronic materials necessitates an understanding and control of chromophore interactions, particularly in their aggregating form. This study presents a customizable molecular design using dissymmetrical ligands to precisely control chromophore interactions through the formation of metal-organic dimers. Anti-paralleled stacking of dissymmetrical ligands in these dimers allows for lateral shifting of chromophore stacking, with the spacing determined and adjusted by ligand dissymmetry. Three metal-organic dimers with varying chromophore spacing exhibited unique photophysical properties and displayed high-efficiency luminescence against quenching. This strategy offers a universally applicable approach to construct chromophore dimers with fixed cofacial spacing and determinate through-space interactions.

Summary: Luminescent metal-radicals have gained attention for their potential applications in materials science. However, the luminescence of metal-radicals tends to decrease after forming metallo-complexes. This study presents a highly luminescent metallo-supramolecular radical cage (LMRC) constructed from a tritopic terpyridinyl ligand RL with a TTM radical and Zn2+. LMRC shows a remarkable photoluminescence quantum yield and high photostability. Additionally, LMRC exhibits significant magnetoluminescence at high concentrations, indicating negligible spin-spin interactions between radical centers.

Summary: This study reports the first example of two pure organic polymorphs with stimuli-responsive single/dual phosphorescence transformation. Efficient intermolecular interactions were found to restrict molecular movements and lock distinct molecular conformations, resulting in different phosphorescence behaviors. Furthermore, single/dual phosphorescence could transform into each other by heating or under solvent vapor conditions, and were used to build logical sensors.
