Towards Main-Chain-Polyoxometalate-Containing Hybrid Polymers: A Highly Efficient Approach to Bifunctionalized Organoimido Derivatives of Hexamolybdates

A NEW LINDQVIST-TYPE HEXAMOLYBDATE CLUSTER FUNCTIONALIZED WITH THE jt-DONOR LIGAND 4-BROMO-2,6-DIMETHYLPHENYLIMIDO: SPECTROSCOPIC, ELECTROCHEMICAL AND STRUCTURAL STUDIES

“…From the synthetic point of view, the C-Br moiety of this new precursor may be useful as an additional reaction site in this type of cluster for a further functionalization through a carbon-carbon coupling reaction, [8][9][10]13 and, potentially, with nucleophilic species to afford new molecular or polymeric hybrid materials.…”

“…2-, a number of new organoimido-derivatives of hexamolybdate, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] hexatungstate, 20 and pentatu ngstenmolybdate, 21 have been synthesized, spectroscopically characterized and, the majority, structurally authenticated by X-ray diffraction analysis. Very recently, the stability, bonding character, electronic properties, first hyperpolarizabilities of this type of complexes have also been studied by Density Functional Theory (DFT).…”

“…, bromo- 12,18 and iodoareneimido hexamolybdates [7][8][9][10][13][14][15] and iodoareneimido pentatungstenmolybdate 21 seems to be of great importance considering their potential applications as precursors for the synthesis of new organicinorganic hybrids containing additional organic 7,8,10,14,15 or organometallic 13 groups, or two similar clusters linked by an extended π-conjugated organic spacer. [8][9][10]15 These halogenated precursors have successfully been applied for the synthesis of organoimido-hexamolybdates as polymer pendants 5 and main-chain polymers.…”

“…[8][9][10]15 These halogenated precursors have successfully been applied for the synthesis of organoimido-hexamolybdates as polymer pendants 5 and main-chain polymers. 9,15 In this paper we report the synthesis, spectroscopic characterization, electrochemical studies and the X-ray crystal and molecular structure of the new organic-inorganic hybrid bearing the electron-withdrawal bromo group in a remote position: (n-Bu 4 N) 2 …”

An Intriguing Morphology Evolution of Polyoxometalate‐Polystyrene Hybrid Amphiphiles from Vesicles to Tubular Aggregates

“…[2][3][4] There have been increasing efforts placed on fabricating POM-containing hybrid polymers by using covalently linked POMs and organic polymers, as the properties of POMs can be significantly improved, such as processability, solubility, stability, and many others. [5][6][7][8][9][10][11][12][13][14][15][16][17] Judeinstein reported the first POM-polymer hybrid where functionalized POMs were used as monomers and their radical polymerization led to the hybrid polymers. [6] Then this approach has been expanded by Mayer and coworkers to prepare POM-polymer cross-linked networks.…”
