Description We have achieved enhanced understanding of charge flow through porphyrin molecular wires. This includes the unique discovery of bias voltage driven conductance increases with length in porphyrin tapes. We have detected mechanochemical atropisomerization within an STM break junction containing porphyrin molecular wires. We have extended single molecule conductance measurements to supra-molecular assemblies including porphyrin nano-rings synthesised by our collaborators. Our collaborating partner has also demonstrated quantum interference in porphyrin nanorings through EPR measurements. In addition, we have studied quantum interference effects in other conjugated systems, such as how cross-conjugation increases the conductance of meta-connected fluorenones and the unusual length dependence of the conductance in cumulene molecular wires.
Exploitation Route This project is providing insights into quantum interference which may be valuable in the field of nano-electronic devices and molecular electronics.

Description As well as laying foundations for understanding charge delocalisation in molecular nanostructures and providing insights into quantum interference which may be valuable in the field of nano-electronic devices and molecular electronics, this project has identified new routes to charge localisation in molecular devices which can be stabilised for longer timescales and operating under ambient conditions. The project has not yet had any economic or societal impact, but has important implications for nanoscale science and molecular electronics since such long-lived charge states might offer future inspiration for redox based molecular memories or memristor architectures. It is fundamental research.
