Insights into organic–inorganic hybrid molecular materials: organoimido functionalized polyoxomolybdates

Abstract

Polyoxometalates (POMs) are polyatomic anions that comprise transition metal group 5 (V, Nb, Ta)) or group 6(Mo, W) oxyanions connected together by shared oxygen atoms. POMs are fascinating because of...

Polyoxometalate‐Soft Matter Composite Materials: Design Strategies, Applications, and Future Directions

“…In class I POM‐polymer hybrids, the components are linked covalently, which can have benefits in terms of stability of the POM‐polymer linkage. [ 43 ] However, due to synthetic challenges in covalently linking POM and polymer, this materials class is still in its infancy. First, organo‐functionalized POMs suitable for covalent linkage to polymers are required, which limits the number of suitable candidates, mainly to Keggin, Dawson, Anderson and Lindqvist ion derivatives.…”

Polyoxometalate templated silver-bisphosphine sandwich: structurally tunable hybrid materials

“…Advanced POM-based functional materials are a complicated and challenging research area. [1][2][3][4][5][6][7] The utilisation of organic ligands or complex units to functionalize POMs is a unique method for generating organic-inorganic hybrid materials based on POMs. [8][9][10][11][12][13][14] These organically functionalized hybrid POMs have been synthesized by replacing one or more oxo or [MoO x ] n+ groups with organic functional groups.…”

“…Polyoxometalates (POMs) are an exceptional group of inorganic compounds that consist of metal-oxygen clusters of early transition metals in high oxidation states (d 0 or d 1 ). [1][2][3][4][5] Polymolybdates are a remarkable family of POMs due to their diverse compositions and structures including [Mo 2 O 7 ] 2− , 6 [Mo 3 O 10 ] 2− , 7 [Mo 4 O 13 ] 4− , 8 [Mo 6 O 19 ] 2− , 9 [Mo 6 O 22 ] 8− , 10 [Mo 7 O 24 ] 6− , 11 [Mo 8 O 26 ] 4− , 12 [Mo 12 O 40 ] 8− , 13 [Mo 14 O 45 ] 6− , 14 [Mo 16 O 52 ] 24− , 15 [Mo 36 O 112 ] 8− , 16 [Mo 154 (NO) 14 O 420 (OH) 28 (H 2 O) 70 ] (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)− with different ratios of mixed valence of Mo VI and Mo V , 17 20 etc. Complexes formed by polymolybdates and first-row transition metal ions tend to exhibit good catalytic activity in redox reactions using hydrogen peroxide (H 2 O 2 ) as an oxidant and have raised wide attention in recent years.…”
