Summary: Amplifying the photoluminescence of lanthanide-doped nanoparticles is important for practical applications. A new iridium-based phosphonate complex is discovered as an ideal antenna material to amplify the near-infrared luminescence of lanthanide-doped nanoparticles. The complex has a quasi-spherical structure and pendent phosphonic groups, which can resist aggregation-caused quenching and firmly anchor on nanoparticles. This complex can stably amplify the luminescence of lanthanide-doped nanoparticles up to 130 times by short-range energy transfer.

Summary: Amplification of near-infrared luminescence of lanthanide-doped nanoparticles can be achieved by a new type of iridium-based phosphonate complex as an antenna. The complex has a quasi-spherical structure and pendent phosphonic groups that resist aggregation-caused quenching and firmly anchor on nanoparticles. The complex can stably amplify the luminescence of lanthanide-doped nanoparticles up to 130 times, potentially due to short-range energy transfer from the complex to lanthanide ions. These findings provide a new fundamental approach to amplify the luminescence of lanthanide-doped nanoparticles and advance their applications.

Summary: This study demonstrates the potential improvement in the efficiency of Eu3+ sensitization in Eu-based MOFs by modifying the antenna ligand. The electronic structure of seven antenna ligand derivatives was examined, and the most likely energy transfer channels for Eu3+ ions in the systems were studied. It was found that introducing a thiophenyl group into the L antenna increased the energy gaps S1 -> T1 and T1 -> 5DJ (Eu3+) to an optimal range for ISC and subsequent energy transfer.

Summary: Complexes of La, Sm, Gd, Er, and Yb with benzophenanthroline-derivative ligands were synthesized via reactions of 8,10-di-tert-butylbenzo[b][1,10]phenanthrolin-11-ol with tris(trimethylsilyl)amide compounds of rare earth metals. X-ray structural analyses revealed the coordination arrangement of the ligand and complexes 2, 4, and 5. The complexes exhibited ligand emission or f-f transition bands depending on the metal ion, and cyclic voltammetry showed multiple redox events corresponding to phenolate moieties oxidation.

Summary: Previously, Lanthanide Luminescent Bioprobes (LLBs) based on pyclen-bearing pi-extended picolinate antennas were synthesized and shown to have suitable optical properties for biphotonic microscopy. This study aims to develop a strategy to design bifunctional analogues of the studied LLBs by adding a reactive chemical group for coupling to biological vectors in deep in vivo targeted two-photon bioimaging. A synthetic scheme was elaborated to introduce a primary amine on the para position of the macrocyclic pyridine unit. Photophysical and bioimaging studies demonstrate that the addition of the reactive function does not affect the luminescent properties of the LLBs, which opens up possibilities for further applications.

Summary: Amines are important compounds present in our daily intake and play a crucial role in controlling physiological functions. The development of sensor devices for monitoring these compounds is an important field of research. This study provides an overview of optical sensors for amine detection, with a focus on fluorimetric sensors based on lanthanide trivalent metal ions. Different matrices for hosting the optical elements are also discussed. Lanthanide complexes are capable of detecting various amines with low detection limits, although there is room for improvement in terms of selectivity and resolution.

Summary: The reaction of 1-methyl-3,4-dihydroisoquinolines with az-lactone provided 2-(3-benzamido-4-oxo-6,7-dihydro-4H-pyrido[2,1-a]isoquinolin-2-yl)-benzoic acids, which were converted into previously unknown dihy-droisoquinoline-naphthyridinones by the action of hydrazine hydrate. Further reaction of the prepared naphthyridine-5,7-diones with POCl3 under various conditions led to the formation of 5-chloro-9,10-dihydro-7H-benzo[c]isoquinolino[1,2-g][1,7]naphthyridin-7-ones or 4,6-dichloro-2-(2-(2-methylprop-1-en-1-yl)phenyl)benzo[c][1,7]naphthyridines. It was also shown that the halogen atom in the C-5 position enters into a substitution reaction with primary and secondary amines.

Summary: Here, we present the redox reactivity of a multimetallic uranium complex supported by triphenylsiloxide ligands, demonstrating the stabilization of low valent synthons through intramolecular ligand migration. The reduction of the diuranium(IV) complex yields U-II/U-IV and U-I/U-IV complexes via ligand migration and formation of uranium-arene delta-bond interactions. Additionally, the reductive coupling of pyridine is achieved through ligand migration, restoring the original ligand arrangement. This work provides a new method for controlling the redox reactivity of unstable, low-valent metal complexes and can contribute to the development of f-elements redox reactivity.

Summary: The biological reduction of soluble U(VI) complexes to form immobile U(IV) species is a potential method for remediating contaminated sites. Multiheme c-type cytochromes (MHCs) have been identified as key mediators of electron transfer to aqueous phase U(VI) complexes in bacteria such as Shewanella oneidensis MR-1. Recent studies have revealed the role of MHCs in the reduction process and the stabilization of U(V)-dpaea species in aqueous solution. This research aims to clarify the involvement of MHCs and determine the mechanism of solid phase U(VI)-dpaea reduction.

Summary: Rigidtritopic linkers were utilized to build porous U-(IV) and Th-(IV) 3D frameworks with tunable charge. Multiple coordination polymers based on U-(IV) and Th-(IV) were synthesized using different trianionic carboxylates as ligands. The structure and dimensionality of the final actinide assembly were influenced by the ligand architecture, pH, stoichiometry, metal nature, and concentration. The synthesized coordination polymers exhibited high surface areas. A crystal-to-crystal transformation from a cationic to a neutral framework was observed during postsynthetic solvent substitution. Rating: 8/10.

Summary: The corresponding N,N'-diamides were obtained by acylation of benzo[c][1,2,5]thiadiazole-4,7-diamine and 2-hexyl-2H-benzo[d][1,2,3]triazole-4,7-diamine with aromatic acid halides, which were then converted into N,N'-dithioamides by reacting with Law-esson's reagent. Previously unknown fused systems, dithiazolobenzo[1,2-c][1,2,5]-thiadiazoles and dithiazolobenzo[1,2-d][1,2,3]triazoles, were prepared by oxidative photochemical cyclization of N,N'-dithioamides. The photo-physical and (spectro)electrochemical properties of the obtained compounds and their polymer films electrochemically deposited on ITO were studied, and the synthesized oligomers showed promising optical contrast and response time for electrochromic devices.

Summary: Significant advances have been made in the chemistry of actinide-nitrides, particularly with uranium and some breakthroughs with thorium. Synthetic routes to uranium nitrides have been identified, but ligands capable of stabilizing them are still limited. Terminal- and bridging-nitrides are attractive for potential reactivity, especially in the field of uranium complexes for dinitrogen reduction and functionalization. Molecular thorium bridged-nitride complexes have recently been discovered, suggesting the possibility of expanding nitride chemistry to low-valent thorium and transuranic elements.

Summary: Understanding the importance of multimetallic cooperativity and alkali ion-binding in the second coordination sphere is crucial for the design of complexes that can facilitate the cleavage and functionalization of dinitrogen (N-2) molecules. In this study, the reaction products and mechanism of N-2 reduction were compared for different uranium(III) complexes with and without alkali ion binding. It was found that the removal of alkali ions enhanced the reducing ability of the complex and led to the formation of new species. Furthermore, the formation of a tetranuclear uranium-N-2 intermediate was proposed, demonstrating the possibility of a three-electron transfer from U(III) to N-2.

Summary: We report the synthesis and characterization of two n-type semiconducting polymers containing a naphthalene diimide (NDI) monomer and thiophene spacers. The introduction of an additional 2,1,3-benzothiadiazole (BTD) moiety in one of the polymers was found to improve charge transport in organic field effect transistors, doping efficiency, conductivity, and stability in the conducting state. Our results highlight the importance of post-deposition annealing in optimizing the doping and thermoelectric properties of BTD-based polymers.
