Studies On Novel Inorganic-Organic Molecule-Based Hybrids-Organoimido Derivatives Of Hexamolybdate

Functional organic-inorganic molecular-based hybrids of metal-oxo clusters (also called polyoxometalates (POMs)) have drawn tremendous attention, in recent years, because of the properties of POMs such as catalysis, storage and transfer of electron and proton, photo/electro -chromism etc. The studies on organoimdo derivatives of POMs in this dissertation are based on POMs as a good electron accepter. More excellent properties of these organoimido derivatives can be adjusted by strong d-π interactions between POM and organic imide ligand, where space occupied by conjugation π electron of the ligand may be extended to the inorganic framework of POM. The aim of this dissertation is to prepare new organoimido derivatives of POMs in the light of the principles of molecule design. The researches on structures, properties and structure-property relationships of the novel compounds will play an important part in explorations and developments of new catalyzers, electric-materials and photoelectric-materials.This dissertation has systemically summarized studies up to date on the functional organic-inorganic molecular-based hybrids of metal-oxo clusters, especially, the syntheses, structures and applications of organoimido derivatives of POMs.In this dissertation, seven new organoimido derivatives has been synthesized by DCC dehydration method with various aromatic amine ligands, which are two mono-functionalized derivatives substituted at terminal oxygens, one trans-bifunctionalized derivative at terminal...
