Summary on Grant Application Form
One of the challenges for modern chemical science is to furnish electronic components on a molecular scale, driven by the continuing impetus for technological miniaturisation. This is typically addressed by employing unsaturated, carbon-rich molecules, which now feature widely in conducting polymers (so-called molecular wires) and as small molecular components of common organic electronics such as OLEDs, field-effect transistors (OFETs) and photovoltaics (OPVs). The incorporation of metals and/or heteroatoms (e.g. nitrogen) into such molecules offers an effective means of enhancing and controlling their photo-activity and conductivity and is thus the subject of significant on-going research. Particular current interest surrounds the use of phosphorus-containing molecules ('phosphacarbons') in such roles, which is being widely investigated. However, the use of phosphacarbons in this context has not yet permeated the organometallic regime; this is due in part to a lack of suitable synthetic methodology and perceived inaccessibility of some of the simplest organometallic phosphacarbons. Recently, the PI has developed the first compounds to incorporate the simplest phosphacarbon fragment 'CP' (cyaphide, the direct analogue of cyanide) as part of a linearly conjugated chain, exploiting an organometallic scaffold. Significant involvement and influence of the cyaphide unit is manifest in the electronic and photolytic behaviour of these compounds (compared with classical carbon-based systems), rendering them of particular interest. This project will build upon these preliminary advances, developing this class of compounds toward achieving electrochemical stability and reversibility of metal-centred redox processes, and exploring their conductive (and photo-absorptive) properties. Further synthetic routes will be investigated and developed to enable access to a broader range of compounds, based on modified organometallic scaffolds, increasing available control over electronic features. The scope for developing more complex phosphacarbon derivatives (e.g. the CC-CP moiety) will also be explored. This project will, therefore, develop the fundamental synthetic science and physical understanding to underpin (directly and indirectly) future developments in the expanding field of applied molecular electronics.
