Summary: In this study, the quaternary ammonium amphiphile A6 was used to encapsulate the europium-containing inorganic polyoxometalate, resulting in a thermotropic liquid crystalline phase with unique structural and properties. The dimerization of carboxylic acid groups facilitated lateral attachment of the mesogens to the inorganic cluster, significantly influencing the thermotropic organized structures of the complex. The luminescence of the polyoxometalate was well retained in the liquid crystalline mesophase.

Summary: Wheat and rice are nutritious grains that contribute 32% of the protein in the human diet worldwide. Genetic modifications to enhance the assimilation of inorganic nitrogen forms into protein have been explored to improve the grain yield of these crops. However, there are still gaps in our understanding of nitrogen metabolism genes, species differences, the impact of soil environments, and the genetic architecture of nitrogen-mediated yield improvement. To continue increasing grain yield and quality, breeding strategies should focus on both carbon and nitrogen assimilation and consider manipulating genes with smaller effects or that are part of regulatory networks.

Summary: This study reports a new family of Zn(16)Ln(HA)(16) metallacrowns with outstanding luminescence properties in the near-infrared (NIR) and suitability for cell imaging. The authors synthesized MCs with two new hydroximate ligands and found that they efficiently sensitize the NIR emissions of Yb-III, Er-III, and Nd-III. The photophysical properties and quantum yields of the MCs were analyzed, providing valuable information for creating MCs suitable for NIR optical imaging.

Summary: This study assessed the cytotoxic activity of camphorimine complexes based on Cu(I), Cu(II), Ag(I), and Au(I) metal sites against ovarian cancer cells. The results showed that the gold complexes exhibited the highest activity, followed by the silver complexes, and then the copper complexes. It was also found that the Ag(I) and Au(I) camphorimine complexes had higher cytotoxic activity than cisplatin. Furthermore, the camphorimine complexes had minimal interaction with DNA compared to cisplatin. The cytotoxic activity of the complexes was directly related to cellular uptake and inversely related to ROS formation.

Summary: Polysiloxane functionalized carbon dots were prepared to improve the stability and photoluminescence of conventional carbon dots. The size of the functionalized carbon dots ranged from 2.2 to 6.4 nm, and their UV-visible absorption spectra shifted to shorter wavelengths with decrease in aminopropyl content in the polysiloxanes. The fluorescence intensities and cores of the functionalized carbon dots varied with the aminopropyl content in the polysiloxanes, indicating tunable photoluminescence. The polysiloxane modification effectively enhanced the stability of carbon dots and allowed for adjustable photoluminescence.

Summary: This study explored the modulation of photocatalytic properties of polyoxometalate-organic hybrids through counterion substitution. The researchers used a series of aromatic sulfonium counterions (ASCs) with different functional substituents to fine-tune the optical bandgaps and adsorption properties of octamolybdate hybrids for photocatalytic dye degradation. They found that the hybrid catalyst with a -CHO substituent exhibited the lowest bandgap and highest degradation rate constant. The study proposed a possible mechanism for photocatalytic dye degradation and identified the intermediates formed during the process.

Summary: Two carborane-containing tetraphenylethylene derivatives were synthesized and their structure-activity relationships were studied. The compounds exhibited aggregation-induced emission effect and their solid-state fluorescence quantum yields and emission colors could be tuned by changing the substituents. Quantum calculations were performed to study the excited electronic structures.

Summary: The use of iminophosphoryl-tethered ruthenium carbene complexes to activate secondary phosphine P-H bonds has been reported. These complexes exhibit different reactivities depending on the electronics of the applied phosphine and the substituent at the iminophosphoryl moiety. Additionally, deuteration experiments and computational studies have shown that cyclometallation is initiated at the M=C bond and triggered by the high electron density at the metal in the phosphido intermediates.

Summary: A series of Cr-dimer compounds with monoatomic chalcogenide bridges have been synthesized. The chalcogenide linkers mediate magnetic exchange between Cr3+ centers, and the ethylenediamine ligands complete the coordination of Cr centers. Antiferromagnetic coupling is observed between Cr3+ centers, and the strength of coupling can be controlled by adjusting the interatomic distances and number of chalcogenide linkers.

Summary: Viruses can interfere with cellular defense by expressing anti-CRISPR proteins. Research using HDX-MS and DSF experiments investigated the interaction between anti-CRISPR proteins and the CRISPR RNA-guided surveillance complex, revealing that AcrIF2 binding relies on enthalpic stabilization, while AcrIF9 uses an entropy driven reaction.

Summary: Two-component organogels and xerogels based on a C-3-symmetric pyrene-containing gelator were deeply characterized through various techniques, with the gelation phenomenon being highly dependent on the nature of the electron poor dopant. The donor-acceptor interactions play a key role in the formation of gels and their spectroscopic properties, showing a remarkable correlation between phase transition temperatures and the disappearance of charge transfer bands. The luminescent properties of these materials can be tuned with temperature, either in intensity or emission wavelength.

Summary: Electrocatalytic CO2 reduction is an effective strategy to reduce atmospheric CO2 concentrations and produce valuable chemical products. Enhancing the activity of molecular systems for these reactions can be achieved by co-catalytic use of redox mediators. In this study, we demonstrate the cooperative effect of inner-sphere mechanism in protic conditions and show that modifying the mediator and ligand design can improve the intrinsic and co-catalytic performance of the Cr-centered catalyst. By optimizing the co-electrocatalytic system, we achieved an enhanced activity at lower overpotentials. This work lays the foundation for developing co-catalytic systems for homogeneous electrochemical reactions.
