Welcome to our website!
We are an experimental materials chemistry group in the Department of Chemistry at the University of Liverpool. Our group is primarily interested in the development of both open and closed shell heterocyclic compounds and their application as advanced magnetic, conductive or photochromic materials. We use organic and inorganic synthetic techniques to generate these materials. We strive to incorporate multifunctional properties into our materials and our research projects range from the study of single molecules up to complex three-dimensional systems.
We study our target compounds using advanced crystallographic techniques via in-house and synchrotron sources. These include structure by powder methods, or by obtaining single crystal data on our materials upon the application of high pressure, at ultra-low temperatures or when irradiated with light. Furthermore, we are interested in the structural ordering of room temperature liquids and the physical properties of “soft” materials probed via SAXS techniques.
Please feel free to browse this site and contact us if you have any questions of enquiries. Finally, please check the opportunities page if you are interested in joining our group.

Crystals of the heterocyclic radical naphtho-1,3,2-dithiazolyl NDTA display magnetic bistability with a well-defined hysteretic phase transition at Tc↓ = 128(2) K and Tc↑ = 188(2) K. The magnetic signature arises from a radical/dimer interconversion involving one of the two independent π-radicals in the P1̅ unit cell. Variable temperature X-ray crystallography has established that while all the radicals in HT-NDTA serve as paramagnetic (S = 1/2) centers, half of the radicals in LT-NDTA form closed-shell N–N σ-bonded dimers (S = 0) and half retain their S = 1/2 spin state. The wide window of bistability (60 K) may be attributed to the large structural changes that accompany the phase transition.
