The on/off-switching of single-chain magnetic behavior tuned through bidirectional light irradiation.
Molecular materials possessing photo-tunable polarization switching is promising for optical switches, smart sensors, and data storage devices. However, it challenging to devise a molecular material featuring simultaneous switchable magnetic dielectric properties with regard non-invasive convenient light stimulus. Herein, we report new Hofmann-type metal-organic framework (MOF) {Fe(bpt)[Pt(CN)4 ]} ⋅ 0.5anth (1, bpt=2,5-bis(4-pyridyl)thiophen; anth=anthracene), which displays thermo-...

A new family of mononuclear Fe(<sc>ii</sc>) compounds is synthesized based on pybox ligands. Their spin-crossover behaviours can be effectively mediated by ligand structures, counter anions, and solvents.
ABSTRACT Electron transfer in solid is crucial to switchable magnetic, electrical, optical and mechanical properties. However, it a formidable challenge control electron-transfer behaviors via manipulation of crystalline phases, especially through dynamic transformation.
