Our work spans the areas of inorganic chemistry, physical chemistry and materials science and focuses on the development of functional inorganic materials which exhibit novel electronic, optical and magnetic phenomena.
Potential applications range from the capture of greenhouse gases to sensors, optoelectronics devices and photocatalysis.
Our key aim is to gain an understanding of the fundamental relationships between the structural features of the solution – and solid – state materials and their physical properties using a barrage of techniques.
This project involves the design and synthesis of metal-organic frameworks that exhibit the highly sought-after properties of redox activity and electronic conductivity. The opportunities for advances at a fundamental and applied level are immense, with potential applications ranging from sensors to molecular electronics devices.
This work seeks to examine the highly novel phenomena arising from the coexistence of electron delocalisation and unpaired spins in framework materials.
The development of more efficient processes for carbon dioxide capture is considered a key to the reduction of greenhouse gas emissions implicated in global warming. We aim to develop highly porous three-dimensional solids known as metal-organic frameworks for use as carbon dioxide capture materials. The ultimate goal is the development of industrially-viable materials which can be readily integrated into industrial processes.
Recently, methodologies for the postsynthetic covalent functionalisation of metal-organic frameworks have opened up fascinating prospects for building complexity into the pores. This project involves the synthesis of materials as “photoswitchable molecular sieves” in which light can be used to modulate the size and polarity of the pores. The structural and physical properties of the materials will require the development of novel techniques to probe the light-activated gas permeation properties.
The complex interplay between electronic and magnetic interactions is ubiquitous in chemical and physical systems (eg. solid-state superconductors, spintronics devices) and in metalloenzymes in nature. Experimental studies in which these phenomena coexist are extremely rare. In this project we will develop dinuclear mixed-valence complexes which incorporate a series of bridging ligands that can mediate strong ferromagnetic “double-exchange coupling” between metal ions with unpaired electrons.
