Research Interest

One important technological goal in the synthesis of materials is to control over the assembly of building blocks from atomic to nanometer scales, directed towards fine-tuning the properties of the bulk material. We propose to attack this problem through the synthesis of well defined building blocks to be used potentially in the synthesis of materials. Our aims are: (i) to develop new methodologies for inorganic synthesis, (ii) to synthesize, isolate, and characterize novel inorganic building blocks (iii) and the rational assembly of these building blocks to engineer new materials. This, we believe, provides an unmatched strategy to control the entire fabrication process: from the selection of molecular precursors for controlled assembly of nanostructures to the conversion of inactive building blocks into a ‘suit-to-purpose’ material.


The compounds synthesized are manipulated and isolated using standard inert-atmosphere glove-box or vacuum-line techniques and characterized a wide variety of spectroscopic techniques. These compounds typically are obtained in multigram quantities as crystalline materials.

Current research projects:

Group 4 mixed-bridge frameworks: In the reaction of RTiCl3 (R= Cp and Cp*) with pyrimidines, compounds containing oxo- and imido-bridges were obtained. This kind of heteroleptic compound is very rare in transition metal chemistry and not previously seen in Group 4. The combination of nitrogen and oxygen bridges within a polynuclear Group 4 compound provides an exciting area for structural, catalytic and reactivity studies.

The possibility of a rational design of transition metal mixed bridge compounds by using oxo-bridge complexes as building blocks opens an exciting path for a wide range of novel Group 4 frameworks (Scheme 1)

Towards 3D inorganic frameworks appended with radicals: The use of molecular magnetic materials provides many opportunities for low-temperature device fabrication and offers an opportunity to tailor the physical properties at a molecular level via general organic synthesis. However, probably the most appealing aspect of molecule-based magnets is that they present several attributes unavailable in conventional metal and metal-oxide magnets, such as low density, solubility in a wide variety of common solvents and/or volatility. These physical properties provide a number of potentially important opportunities in low temperature processing techniques such as electro-coating, evaporation and chemical vapor deposition.

We are working towards the rational assembly of large macromolecular systems with multiple spin carriers. We have started functionalizing dimeric phospha(III)zane [ClP(µ-Npy)]2 with dithiadiazolyl radicals in an attempt to synthesize the units that will form part of these macrocycles. The formation of macrocycles and the possibility of 3D structural arrangements would open this area to radical functionalized nanotubes.
