Cobalt- and Nickel-based Polymetallocenes: Functional Metallopolymers from Earth-Abundant Metals

Lead Research Organisation: University of Oxford
Department Name: Oxford Chemistry


The field of polymers containing metal atoms as part of the structure (metallopolymers) is relatively new in comparison to that of polymers in general. Nevertheless, recent advances in this area have established metallopolymers as an attractive class of easily processed materials in which metal centres introduce properties and functions that complement those available with state-of-the-art organic macromolecules. This proposal outlines a research programme to synthetically develop and to understand the properties of two new classes of metallopolymers based on the metals cobalt and nickel, and also to lay the foundations for their exploitation, with a particular focus on their antimicrobial and magnetic properties. The development of new antibiotics is of key global importance due to the reduced effectiveness of currently available compounds towards infection. In addition, the development of easily processed polymeric materials that function as magnets is particularly desirable for a range of applications in computers and other devices.

Description New Magnetic Organometallic polymers have been prepared. Solid state magnetic measurements have been preformed, the homopolymers behave as simple paramagnets at temperatures greater than 50 K, with significant antiferromagnetic coupling that is notably larger in carbon-bridged compared to the disilyl-bridged analogues. However, the behaviour of the polynickelocenes deviates substantially from the Curie-Weiss law at low temperatures due to considerable zero-field splitting.

A paper in internationally peer review journal has been published.
