Heavily conjugated, carbon-rich organometallics continue to feature prominently in efforts to achieve molecular-scale conductors (so-called ‘molecular wires’) and other electro-active molecular-scale components. Currently gaining prominence in this field are efforts to produce ‘doped’ analogues of these, featuring discrete low-coordinate main-group atoms, an area in which we have been interested, with specific focus on phosphorus derivatives. This project will continue and extend these studies to include other main-group fragments.
The project builds on our recent work with the synthesis and study of conjugated organometallic complexes and ligands incorporating phosphacarbon fragments (see for example Dalton Trans. 2019, 48, 8131; Inorg. Chem. 2019, 58, 14800; J. Org. Chem. 2020, 85, 14697; Chem. Eur. J. 2021, 27, 16342). Initial studies will exploit some recently discovered reduction chemistry of [Ru(dppe)2(CP)]+ as a means of generating anionic cyaphide-containing transition metal reagents, to facilitate fragment coupling reactions and the incorporation of further main-group components within the conjugated framework. These systems will be studied for their electrochemical response, guiding subsequent targets, with complementary investigation of chemical reactivity, directed toward the development of electronically distinctive ligand frameworks.
The project will involve substantial anaerobic synthesis of organometallics and ligands, with extensive ‘hands-on’ use of advanced multinuclear NMR spectroscopic techniques as a primary means of compound characterisation and reaction monitoring. Electrochemical studies (CV, spectro-electrochemistry) will be undertaken (with relevant training) and there will be the opportunity (if so wished) to learn X-ray diffraction and DFT techniques.
