Hybrid Organic−Inorganic Polyoxometalate Compounds: From Structural Diversity to Applications
TLDR
Polyoxometalates (POMs) are discrete anionic metaloxygen clusters which can be regarded as soluble oxide fragments which play a great role in various areas ranging from catalysis, medicine, electrochemistry, photochromism,5 to magnetism.Abstract:
Polyoxometalates (POMs) are discrete anionic metaloxygen clusters which can be regarded as soluble oxide fragments. They exhibit a great diversity of sizes, nuclearities, and shapes. They are built from the connection of {MOx} polyhedra, M being a d-block element in high oxidation state, usually VIV,V, MoVI, or WVI.1 While these species have been known for almost two centuries, they still attract much interest partly based on their large domains of applications. They play a great role in various areas ranging from catalysis,2 medicine,3 electrochemistry,4 photochromism,5 to magnetism.6 This palette of applications is intrinsically due to the combination of their added value properties (redox properties, large sizes, high negative charges, nucleophilicity...). Parallel to this domain, the organic-inorganic hybrids area has followed a similar expansion during the last 10 years.

TL;DR: The results show that the organoimido-POM unit is an efficient acceptor for second-order NLO, but an ineffective donor, and the nature of electronic transitions in arylimido- POMs is strongly influenced by the substituents of the aryl group, but lose their advantage with extended π-conjugation.
