Summary: Methodologies for synthesizing the first generation of 3-nitro-1,8-naphthalimides containing nido and closo moieties are reported. Boron-containing compounds were synthesized by reacting 3-nitro-1,8-naphthalic anhydride with ammonium derivatives of nido and closo ions. A novel boron-enriched mitonafide was obtained through nucleophilic ring-breakdown reaction. These synthesized compounds have potential as agents for boron neutron capture therapy for cancer.

Summary: closo-Carboranes have been extensively studied for their wide applications in medicine, catalysis, and energy storage. This study investigates the physical nature of interactions involving (R-CB11H11-, R = H, F, CH3, CF3) and Mq+ = Li+, Na+, Mg2+, Zn2+ ions to gain insights into the physics behind the interactions of oppositely charged ions. The findings reveal significant electrostatic and orbital contributions in such complexes, and that the strength of ionic pair interactions (R-CB11H11- <-> Mq+) is more dependent on the nature of the cation employed rather than the substituent R used. Charge transfers are not significant in these interacting systems.

Summary: This research presents a simple and effective method for preparing silver closo dodecaborate (Ag2B12H12) films using an electrochemical route. The size of the Ag2B12H12 particles in the films can be controlled by adjusting the electrochemical parameters. Ag nanoclusters with controllable sizes can be generated by electrochemical reduction reactions or thermal anneal. These Ag nanoparticles show promising performance for hydrogen evolution reaction (HER) in an acidic solution. This study provides new insights into the synthesis of [B12H12](2-) based thin films, the generation of metal nano-powders, and their application in HER or other applications.

Summary: Two new approaches were developed for the functionalization of the 1-carba-closo-decaborate anion [1-CB9H10](-) at boron atoms. The first approach involved the ring-opening of its 1,4-dioxane derivative with various nucleophiles, while the second approach involved the Pd-catalysed cross-coupling of its iodo derivative with aromatic amines and heteroaromatics.

Summary: In this work, an electrochemical study of the Boron cage monomercaptoundecahydro-closo-dodecaborate [B12H11SH](2-) in solution and in a self-assembled monolayer over a gold electrode was conducted. The study revealed the interaction between the boron cage and the gold surface, formation of a self-assembled monolayer, and the reduction of active sites on the gold surface due to the presence of the boron cage. Bulkier thiols were found to enhance charge accumulation at the electrode-solution interface.

Summary: Novel amphiphilic compounds with dianionic head and alkoxy tail were synthesized to challenge the classical concept of step-like micellization. The surfactants self-assembled to form small micelles with decreasing aggregation number at higher concentration. Extensive counterion binding was observed in the micelles, and a three-step thermodynamic model was used to estimate the parameters associated with micellization process. The concept of step-like micellization was found to be inappropriate for these types of micelles.

Summary: Introducing B12H12Cs2 can improve the defects and strain of the buried SnO2/perovskite interface and enhance the performance of n-i-p type perovskite solar cells. B12H12Cs2 can passivate the bilateral defects of the buried interface and promote the charge transfer and extraction efficiency. Additionally, it can improve the crystal properties of perovskite films and release the buried tensile strain.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: Isomorphous series are generated by replacing atoms or molecules to form materials with similar compositions. They allow modulation of structure and properties, and generate equivalent compositions with novel material properties.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
