The development of molecular materials whose physical properties can be controlled by
external stimuli—such as light, electric field, temperature, and pressure—has recently …

The defining characteristic of a valence tautomeric (VT) transition in a metal complex with a
redox-active organic ligand is a stimulated intramolecular electron transfer between metal …

The mechanism of cobalt (II)− porphyrin-mediated cyclopropanation of olefins with
diazoesters was studied. The first step reaction of cobalt (II)− porphyrin with ethyl …

A viologen‐based Borromean entangled porous framework was found to be sensitive to
both CuKα and MoKα X‐ray sources, showing rapid photochromic response and recovery …

Addressing individual bistable magnetic molecules, known as Single Molecule Magnets
(SMMs), is a fascinating goal at the borderline between molecular magnetism and spin …

A photochromic compound with fast response to Mo-Kα (4 min) and Al-Kα (1 s) X-rays was
synthesized using a cluster of high-Z atoms and a flexible viologen zwitterion. The coloration …

Using X-ray absorption techniques, we show that temperature-and light-induced spin
crossover properties are conserved for a submonolayer of the [Fe (H2B (pz) 2) 2 (2, 2 …

A color change: X-ray-induced photochromic species are rare and can be used for detection
of X-rays. A highly robust X-ray-sensitive material with the discrete structure of a metal …

Electronically labile, or switchable, cobalt coordination polymers exhibit reversible spin
crossover (SCO) or valence tautomeric (VT) transitions upon the application of an external …

Chiral drugs play an important role in modern medicine, but obtaining pure enantiomers
from racemic mixtures can pose challenges. When a drug is chiral, only one enantiomer …
