It has been clearly demonstrated that solution-based synthesis of nanoparticles or nanocrystals is a promising simple and benign method providing a number of advantages compared to the physical synthetic approaches. Such a chemical method is, indeed, classical to synthesize metal-based nanomaterials. In marked contrast, although the group-14 element based nanomaterials (C, Si, Ge) are also an exciting class of materials with a range of biomedical and optoelectronic applications, the major synthetic methods for them are still conventional physical or thin film methods. This situation is certainly due to the lack of appropriate precursors which can be easily decomposed to generate the corresponding atomic elements (C, Si, Ge) in mild conditions.
In the course of this project, to address this issue, we will develop appropriate precursors, notably thermally labile low-valent Si- and C-complexes (for example, L→SiR2, L→C←L, L = electron donating ligand), allowing to easily synthesize various Si- and C-nanomaterials using classical chemical synthetic techniques. The success of this project should provide to most of synthetic chemists an easy access to the research on Si- and C-nanomaterials, and thus should considerably accelerate their development.
1-The synthesis of various thermally labile Si- and C-complexes and the test of their use as precursors of nano-materials.
2-Analysis of obtained nanomaterials and optimization of reaction conditions.
The candidate must have a solid background in molecular chemistry (organic and organometallic chemistry). Good skill in manipulations with highly reactive molecules (air-sensitive complexes) will also be required.
This research is conducted in frame of the international collaborative research program between French (T. KATO at Toulouse University) and Singaporean (Prof. C.-W. So and Prof. H. J. Fan at NTU) teams founded by ANR and NRF for a period of three years (2019-2021).
