Project Details


There is an urgent need for the development of materials that can effectively bridge living systems with electronics for biomedical applications. This EPSRC-funded Bridging the Gap project investigated a new class of gel-phase materials that could be ideally suited for this purpose. These materials are composed of hybrid biomolecular/organic building blocks that spontaneously assemble into conducting nanotubular networks. This project was followed by two 10-week EPSRC Vacation Bursaries (in 2012 and 2013) led by Gleskova and in collaboration with Ulijn and Skabara.

Key findings

Initially, electrical conductivity of xerogels based on two newly developed materials, TTF-LLL-OMe and TTF-LLL-OH, was investigated as a function of temperature and iodine doping. The electrical conductivity of the as-deposited TTF-LLL-OH was thermally activated with the activation energy of ~ 0.47 eV. After exposure to iodine, the conductivity lost its thermally-activated character for temperatures above ~ 30⁰C.

Later, assembly of TTF-FF-NH2 in several organic solvents was studied. AFM, FTIR and UV-Vis-NIR spectroscopy confirmed the presence of ordered nano-structures in the gel in several instances. The gel exhibited electrical conductivities with thermally activated character in both undoped and iodine-doped state.
