Article Synopsis
- - The study involves the self-assembly of a heteropolyoxomolybdate compound and a pyridyl-based diarylethene, resulting in a molecular capsule that is photo-active, specifically designed for efficient light-induced processes.
- - The arrangement of the diarylethene ligands is influenced by the chemistry of the metal oxide, allowing only a specific form to bond with the polyoxometalate, and the stability of this assembly in solution is confirmed by various spectroscopic methods.
- - Research reveals a photochemical sequence where light triggers the closing of the diarylethene structure, followed by electron transfer to the polyoxometalate, supported by sophisticated analyses and a setup for measuring quantum yields.
Polyoxometalates (POMs) are anionic molecular metal oxides with expansive diversity in terms of their composition, structure, nuclearity and charge. Within this vast collection of compounds are dominant structural motifs (POM platforms), that are amenable to significant chemical tuning with minimal perturbation of the inorganic oxide molecular structure. Consequently, this enables the systematic investigation of these compounds as inorganic additives within materials whereby structure and charge can be tuned independently [PWO] [SiWO] while also investigating the impact of varying the charge balancing cations on self-assembly.

Single-crystal XRD on Na[Mn(HO)(PWO)]·84HO () revealed that four Mn ions form a rhombic MnO core encapsulated by two [PWO] units.
