Advanced Science, EarlyView.This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Supramolecular Enforcement of Planar Tetracoordinate Halides
Angewandte Chemie, EarlyView.A calix[4]pyrrolato‐indium scaffold preorganizes Li4 pockets that trap Cl−, Br−, and I− in strongly flattened to square‐planar tetracoordinate environments. Computations reveal low planarization energies for the heavier halides, while crystallography shows that their geometry is readily modulated by subtle supramolecular and packing effects ...

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides
Advanced Science, EarlyView.Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...

Angewandte Chemie, EarlyView.Lenacapavir, the first‐in‐class drug targeting HIV‐1 capsid, is a breakthrough drug in HIV‐1 treatment and prophylaxis. However, a single M66I mutation confers complete viral resistance to lenacapavir. We report herein the design and synthesis of innovative R2 analogs demonstrating low nM potency against HIV‐1 M66I and excellent pharmacokinetics in ...

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)
Angewandte Chemie, EarlyView.Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote
