PI Contribution A new conjugated molecule has been synthesised and is being studied for its single molecule conductance using the break-junction method.
Collaborator Contribution The collaboration is with Prof Latha Venkataraman from Columbia University, USA. The partners are experts in studying single molecule conductance using the break-junction method. They are carrying out such measurements on two new materials made from the Skabara group. This method is an alternative way of characterising the conductance of target molecules, compared to the methods applied by our co-investigators in Oxford.
Impact We have discovered a new chemical design principle for exploiting destructive quantum interference. The approach has provided a six-nanometer single-molecule switch where the on-state current is more than 10,000 times greater than the off-state current - the largest change in current achieved for a single-molecule circuit to date. The work is multi-disciplinary and involves chemistry (Glasgow) and applied physics (Columbia). The work has been published in Nature Nanotechnology and has received significant coverage in the scientific press (Physicsworld, Science Bulletin, EurekAlert!, ScienMag, Science Daily, Brinkwire, sciencenewsnet.in, Nanowerk, Newswise, Phys.org, Scitech Daily, Bioengineer.com).
