Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

Yb2‐Tb Upconversion in a Hetero‐Trimetallic Molecular Lanthanide Complex
Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.Lanthanides are at the forefront of photon upconversion in molecular systems; however, the chemical nature of the lanthanides makes site‐specific coordination chemistry difficult to achieve. Here, we employ kinetically stabile building blocks to achieve hetero‐trimetallic 4f complexes with complete site‐specific chemical control.

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics
Nanophotonics, Volume 15, Issue 5, 16 March 2026.Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly
