Summary: The reactivities of o-carborane-fused silylenes towards molecules with CE (E = C, P) bonds were studied. Reactions of [(LSi:)C]2B10H10 (1a) with arylalkynes resulted in the formation of bis(silylium) carborane adducts 2 and 3. On the other hand, the reaction of 1a with a phosphaalkyne AdCP led to the synthesis of compound 4, featuring fused CPSi rings with a C=Si double bond and Si-Si single bond. Furthermore, the reaction of monosilylene 1b with AdCP yielded compound 5, containing a 1,2,3-triphosphetene core. The structures of the products were characterized by NMR spectroscopy and/or X-ray crystallography.

Summary: The recent success in the development of non-fullerene acceptors (NFAs) for organic solar cells (OSCs) has led to a search for efficient and complementary donor materials. Understanding the structure-property correlations for new generations of acceptor and donor materials is crucial for advancing the field of OSCs. This study reports the synthesis and investigation of star-shaped small molecules based on benzotriindole (BTI) as potential donor materials for NF OSCs.

Summary: Directing the self-assembly of small organic molecules into low-dimensional porous patterns is a versatile method for fabricating flat nanomaterials with controllable architecture and functions. In this study, the surface-confined self-assembly of tripodal polytopic molecules was investigated using computer simulations. By altering the number and position of sticky sites on the molecules, various supramolecular constructs were observed. These findings are relevant to experimentalists seeking new linkers for constructing surface-supported supramolecular constructs.

Summary: The paper investigates a class of nonconvex-constrained differential hemivariational inequalities consisting of nonlinear evolution equations and evolutionary hemivariational inequalities. The admissible set of constraints is closed and star-shaped with respect to a certain ball in a reflexive Banach space. The existence results are obtained by constructing an auxiliary inclusion problem and applying a surjectivity theorem for multivalued pseudomonotone operators and the properties of Clarke subgradient operator. Moreover, the existence of a solution to the original problem is established by the hemivariational inequality approach and a penalization method. A provided application of the main results.

Summary: Three p-type small molecules based on tetraphenylethylene core and fused ring-terminated diarylamine electron donating groups were synthesized and investigated for use in inverted perovskite solar cells. Among them, the CL-3 molecule showed the highest efficiency due to its smooth surface morphology, better charge transfer, and energy-level alignment. This work demonstrates the potential for developing highly efficient solar cell performances using the bilayer HTL strategy.

Summary: Films made of poly (epsilon-caprolactone) (PCL) are highly regarded in biomedical applications due to their biodegradability, biocompatibility, flexibility, and non-toxic degradation by-products. This study explores the switching behavior of PCL surface morphology under various conditions and found that factors such as substrate polarity, polymer molecular weight, solvent annealing, and thermal annealing all influence morphology transition. The molecular weight of the polymer, solvent annealing, and thermal annealing can affect the surface domains and long-range ordering of PCL chains, while different solvents vapor will lead to different outcomes in film morphology.

Summary: Transition metal-catalyzed reactions of silacyclobutanes with a variety of pi units have become a straightforward and efficient approach to access structurally diverse organosilicon compounds. However, the reaction of silacyclobutanes with alkynes still faces limitations, such as challenging internal alkynes, expensive catalysts, and lack of control over chemodivergence. In this study, a nickel-catalytic system is introduced, which overcomes these limitations and provides complementary substrate scope, ligand-controlled chemodivergence, and low cost. Ligand steric effects play a crucial role in determining the selectivities of different reaction pathways.

Summary: This study presents a general palladium-catalyzed monoacylation method for carbazoles, using toluene derivatives as both acyl source and organic solvent, with NHPI and oxygen as cocatalyst and sole oxidant, respectively. The regioselective acylation at C-8 position of monosubstituted N-pyridylcarbazoles is achieved using aldehyde as the acyl source, indicating a highly site-selective acylation proceeding through a radical process.

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: Boron-rich glycodendrimers containing multiple glucose moieties and ortho-carborane clusters were synthesized and found to be completely water soluble due to increased hydrophilicity. In vitro evaluation showed that the glycodendrimer with nine glucose moieties exhibited the highest cytotoxicity against MCF-7 breast cancer cells, with a 600-fold higher potency than cisplatin. The study suggests that these glycodendrimers could serve as tumor-specific anticancer agents.

Summary: Carboxyboranylamino ethanol was prepared with a 75.0% yield through an amine-exchange reaction. It showed lower cytotoxicity and higher anti-tumor efficacy in vitro compared to 4-borono-l-phenylalanine (BPA) and methyl 2-hydroxyl-5-(1'-ortho-carbonylmethyl-1',2',3'-triazol-4'-yl)-benzonate (2). The bio-enhancement was explained using molecular docking calculations.
