ORGANOMETALLIC POLYMERS

Organometallic materials containing conjugated carbon ligands are emerging as interesting new materials for use in advanced technologies. Molecular wires, Liquid Crystalline and Non Linear Optical materials have all been touted as potential uses of these conjugated materials. Third order NLO effects occur in extended p-conjugated systems and appear to be directly related to the number of atoms in long chain molecules. The requirement of reliable synthetic procedures to materials of this type precedes the fabrication of useable devices. Molecular scale connectors are significant because they provide the basis for new technology that will supplant current practices in the fabrication of microelectronic devices.

Established technology has embraced the goal of ultra-miniaturisation of electronic components on microchips but there is undoubtedly a physical limit to this approach. The chemical approach is to make successively larger molecules whose physical dimensions will approach the size of the smallest microelectronic components. Connection between existing components and the smallest attainable components could be achieved by the employment of so-called molecular wires The molecular wire is a simple electronic device that acts as a charge carrier. Electrical conduction carries the requirement for conjugation along the entire length of the wire as well as a small band gap between the localised and delocalised electrons.


NEW CATALYSTS FOR GAS-TO-LIQUIDS CONVERSION

The chemical conversion of natural gas into high molecular weight hydrocarbons via oxidative coupling or partial oxidation into oxygenates currently represents a great chemical and technological challenge for the petrochemical industry. These processes utilize a number of different catalytic systems. The systems and the basic principles of the two types of processes are well known. However, a greater effort is needed towards the development of more efficient and stable catalysts to operate under the severe conditions imposed by the catalytic reaction itself, as well as the need for suitable reaction design to minimize the extent of the homogeneous reaction.

An alternative process is to obtain synthesis gas (CO/H2) through steam reforming followed by a second Fischer-Tropsch (FT) hydrogenation step. However, the unfavorable energetic balance of the reforming step and the absence of selective catalysts in the latter, to obtain a narrow molecular weight distribution, currently lead to a compromise in solutions. The use of synthesis gas (syngas) derived from the North West Shelf gas reserves offers the opportunity to furnish a broad range of environmentally clean fuels and chemicals and is known as Gas-to-Liquids technology. The Fischer-Tropsch synthesis remains the third largest consumer of syngas, mostly for the production of transportation fuels but also as a growing feedstock source for the manufacture of chemicals, including polymers.

Highly dispersed supported metal catalysts have been shown to be important in hydrocarbon synthesis via the Fischer-Tropsch (FT) process. Metals important in FT catalysis are Fe, Co, Ru and Os and to a lesser extent Ir, Rh and Pt, which have lower catalytic activity. Catalyst modification allowing control of chain growth and inhibition of alkene hydrogenation has been achieved by high dispersal of catalysts, the use of shape selective catalysts (aluminosilicates or Zeolites) and considerable selectivity has been gained by using bimetallic catalysts

This project will involve the preparation of novel molecular bi-metallic complexes which will be anchored onto the exciting new class of mesoporous silicas called the M41S materials, the diagram is that of one member of this family, MCM-41. These supported materials will then be calcined to provide new catalytic materials which will then be characterised by a variety of techniques including TEM, SEM, XPS.


USEFUL POLYMERS BY CLEAN TECHNOLOGY: POLYMERISATION IN SUPERCRITICAL FLUIDS

Transition metal based homogeneous catalysts are renowned for their excellent tunability and recently polyketones have been produced industrially as a new class of synthetic materials with superior properties.

This project involves the exploration of polymerisation chemistry, particularly CO/ethylene, in supercritical carbon dioxide (scCO2). The unique physical properties associated with scCO2 give rise to an intriguing range of possibilities for the materials chemist. There are a range of chemical, environmental and economic advantages to be gain from the use of scCO2. Its pre-eminence as a clean “solvent” which is re-cyclable is a major consideration. The methodology to be applied relies on the introduction of fluorinated alkyl groups to existing precatalysts to make them more soluble in scCO2 and the preparation of new catalysts.
