“…The non-covalent approach is based on van der Waals or Coulombic interactions and does not need POM prefunctionalization. Since POMs are anionic clusters, they can form electrostatic complexes with cationic chromophores such as Ru or Re polypyridyl complexes, [3][4][5] organic dyes, [6][7][8] or porphyrins and phthalocyanines. [9][10][11] POM-porphyrin coordination complexes were also reported.…”

Hybrid polyoxometalate-porphyrin copolymeric films were obtained by the electro-oxidation of zinc octaethylporphyrin (ZnOEP) in the presence of a Dawson type polyoxophosphovanadotungstate bearing two pyridyl groups (POM(py)2). The synthesis of a series of POM(py)2 consisting of [P2W15V3O62](9-) functionalized with diol-amide or triol moieties, as well as the characterization of the copolymers are presented.

“…Previously, one well understood synthetic method was to incorporate lanthanide ions, mainly Eu 3+ and Tb 3+ , into POMs171819202122. Alternatively, the introduction of organic fluorophore may be an efficient synthetic strategy and have been attracted much attention in the past decade23242526272829303132. Especially, the organic functionalization of POMs via covalent linkage to form organic-inorganic hybrid fluorescent materials is a very attractive and challenging research area.…”

A novel monosubstituted organoimido hexamolybdate containing 6-nitroquinoline moiety has been successfully synthesized. This organically-functionalized polyoxometalate exhibits proton-induced switchable fluorescence property in aqueous acetonitrile solution at room temperature. Experimental and theoretical investigations of this reversible “on” and “off” switching mechanism have been carried out, and it is found that the protonation and deprotonation at the heterocyclic nitrogen atom within quinoline fragment leads to the breaking and reformation of the conjugation through strong d-π interaction between the hexamolybdate anionic cluster and the quinoline moiety, resulting in “on” and “off” luminescence signal.
