Polyoxometalates (POMs) are interesting inorganic compounds that contain transition metal ions linked together by bridging oxygen atoms to form large three dimensional frameworks. Even though POMs have been studied for a long time (the first polyoxometalate was reported nearly 200 years ago by the Swedish chemist, Jons Jacob Berzelius), there has been limited success in producing practical and functional materials.
By replacing the oxo bridging groups with organic ligands, researchers can develop new strategies for synthesising novel POM-based organic-inorganic hybrid materials through linking POMs and organic compounds together by covalent bonds. Of particular interest are the organoimido POM derivatives.
In their latest HOT Perspective article, a team of researchers from Tsinghua University, China, explore the synthetic chemistry of organoimido derivatives of POMs and the reactive chemistry for the construction of POM-based hybrid materials. Wei et al. highlight that both the inorganic cluster skeleton and the organic ligand in organoimido-based POMs can act as reactive sites which could lead to an exciting future for the chemistry of organoimido based POMs.
