Embodiment 1

[0044] 1) Synthesis of polymolybdenum oxide cluster-maleimide hybrids.

[0045] Dissolve 0.21g of 3-maleimidopropionic acid and 0.44g of 2-ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline in 50mL of acetonitrile, heat up to 81°C and stir for 20min , Add 1g of polymolybdenum oxide clusters to react for 24h, stop the reaction. After the reaction product was concentrated by rotary evaporation, it was added to precipitate in chloroform, and the separated precipitate was dissolved in 7 mL of acetonitrile, placed in ether vapor to precipitate, filtered by suction, and dried in vacuum to obtain 0.95 g of polymolybdenum oxide cluster-maleimide hetero Compound orange solid, yield 82%.

[0046] figure 1 It is the H NMR spectrum of the polymolybdenum oxygen cluster-maleimide hybrid. The * in the spectrogram indicates the solvent peak, and all the characteristic peaks are clearly assigned, and there are no miscellaneous peaks in the spectrogram, which proves that the prepared polymolybden...

Abstract

The invention discloses a poly-molybdenum oxygen cluster-polyethylene glycol hybrid. The poly-molybdenum oxygen cluster-polyethylene glycol hybrid is shown as a general formula (III) in the description, wherein POM=MnMo6O18, TBA=[(C4H9)4N]<+>, and n=20 to 50. The poly-molybdenum oxygen cluster-polyethylene glycol hybrid is prepared by performing a Diels-Alder reaction on methoxy polyethylene glycol and a poly-molybdenum oxygen cluster-maleimide hybrid. The prepared hybrid has high solubility in solvents of different polarities, and has high physical compatibility with high-molecular materials such as polyvinyl alcohol.

Description

technical field [0001] The invention belongs to the technical field of material chemistry and relates to a polymolybdenum oxycluster hybrid, in particular to a polymolybdenum oxycluster-polyethylene glycol hybrid prepared by a click chemistry method. Background technique [0002] With the rapid development and replacement of high-tech, the traditional single-performance polymer or inorganic materials are increasingly unable to meet people's needs for materials. In order to solve this contradiction, an effective way is to prepare different types of functional materials into corresponding hybrid materials through chemical methods, so that on the basis of retaining the advantages of each original component, through the synergistic effect between each component , to overcome the shortcomings of the original components, to promote the performance of each component to complement each other, to improve the performance of the material, to make its overall performance better than tha...
