Abstract Cuproptosis, an emerging form of programmed cell death, has received tremendous attention in cancer therapy. However, the efficacy cuproptosis remains limited by poor delivery efficiency copper ion carriers. Herein, complex nanoparticles (denoted as Cu(I) NP) are developed that can efficiently deliver into cells to induce cuproptosis. NP demonstrate stimulus‐responsive release complexes, which results mitochondrial dysfunction and promotes aggregation lipoylated dihydrolipoamide S‐acetyltransferase (DLAT), leading Notably, not only cuproptosis, but also elicit robust immune responses suppress tumor growth. Overall, this study provides a promising strategy for cuproptosis‐based

Chiral atomically precise metal clusters, known for their remarkable chiroptical properties, hold great potential applications in chirality recognition. However, advancements this field have been constrained by the limited exploration of host–guest chemistry, involving clusters. This study reports synthesis a chiral Cu16(C2B10H10S2)8 (denoted as Cu16@CB8, where C2B10H12S2H2 = 9,12-(HS)2-1,2-closo-carborane) cluster an achiral carboranylthiolate ligand.

The development of new synthetic methods for B–H bond activation has been an important research area in boron cluster chemistry, which may provide opportunities to broaden the application scope clusters. Herein, we present a reaction strategy direct site-selective functionalization nido-carboranes initiated by photoinduced cage via noncovalent cage···π interaction. As result, nido-carborane radical is generated through single electron transfer from 3D 2D photocatalyst upon irradiation with green light. resulting transient could be directly probed advanced time-resolved EPR technique. In air, subsequent transformations active have led efficient and selective B–N, B–S, B–Se couplings presence N-heterocycles, imines, thioethers, thioamides, selenium ethers. This protocol also facilitates both late-stage modification drugs synthesis nido-carborane-based drug candidates neutron capture therapy (BNCT).

Heteroleptic metal–organic capsules, which incorporate more than one type of ligand, can provide enclosed, anisotropic interior cavities for binding low-symmetry molecules biological and industrial importance. However, the selective self-assembly a single mixed-ligand architecture, as opposed to numerous other possible outcomes, remains challenge. Here, we develop design strategy subcomponent heteroleptic architectures with internal void spaces. Zn6Tet3Tri2 triangular prismatic Zn8Tet2Tet′4 tetragonal were prepared through careful matching side lengths tritopic (Tri) or tetratopic (Tet, Tet′) panels.

ConspectusMetal nanoclusters, distinguished by their atom-precise structures and quantum size effect, are regarded as a crucial bridge between organometallic complexes plasmonic metal nanoparticles. These nanoclusters primarily composed of metallic core enveloped protective ligands, wherein the ligands play vital role in determining nanoclusters' synthesis, structural integrity, physicochemical properties. Considerable efforts ligand engineering have concentrated on exploring novel coordinating functional groups to advance nanocluster research, particularly precise controlled synthesis superatomic fine-tuning intrinsic properties, subsequent assembly application. However, backbone these seems equally important but attracts less attention. It is reasonable that if utility two moieties (coordinating group backbone) provokes profound synergistic contributions properties resultant extremely inestimable. In this context, carborane, with its spherical shape three-dimensional aromaticity (electronic effect), has emerged promising candidate for design. Over past decades, incorporation carborane into enabled construction various exhibiting distinct architectures, enhanced stability, unique reactivity. Therefore, it present current status challenges associated carboranyl ligand-protected guide future development. This Account provides comprehensive summary recent advances ligand-stabilized primary focus from our laboratory. We begin discussing advantages introducing carborane-based preparation, particular emphasis virtues heterometal-doped isostructural nanoclusters.

Abstract Hypergolic propellants rely on fuel and oxidizer that spontaneously ignite upon contact, which fulfill a wide variety of mission roles in launch vehicles spacecraft. Energy‐rich carboranes are promising hypergolic fuels, but triggering their energy release is quite difficult because ultrastable aromatic cage structure. To steer the development carborane‐based high‐performance material, carboranylthiolated compounds integrated with atomically precise copper clusters presented, yielding two distinct isomers, Cu 14B‐S 14C‐S , both possessing similar ligands core structures. With migration thiolate groups from carbon atoms to boron atoms, ignition delay (ID) time shortened 6870 3 ms when contacted environmentally benign high‐test peroxide (HTP, H 2 O concentration 90%). The extraordinarily short ID ranking among best HTP‐active materials. experimental theoretical findings reveal benefitting groups, characterized by an electron‐rich metal kernel, displays enhanced reducibility superior charge transfer efficiency. This results exceptional activation rates HTP, consequently inducing carborane combustion simultaneous energy. fundamental investigation shed light advanced green propulsion systems.
