Research Interests

We are principally interested in the fundamental synthetic, chemical and physical properties of luminescent compounds. They are characterised by spectroscopic (NMR, IR, UV-vis, MS, Raman), computational (DFT) and diffraction (X-ray) methods available from the excellent departmental research facilities here along with (spectro)electrochemical and photophysical measurements to explore their emission properties. Luminescent compounds of interest include ON/OFF photoswitches, phosphorescent metal complexes and thermally activated delayed fluorescence (TADF) molecules.


Prompt fluorescence molecules
Carborane ON/OFF switch

Compounds containing carboranes (stable clusters of boron, carbon and hydrogen) have intriguing photophysical properties. Some derivatives of ortho-carborane (1,2-C2B10H12) have dual emissions where one emission is due to charge transfer (CT) or excimer/aggregation formation.

Phosphorescent complexes
Iridium PHOLED performances

Certain metal complexes are used as emitters in phosphorescent organic light-emitting diodes (PHOLEDs). Iridium complexes are shown to emit desirable blue colours and can be incorporated in PHOLEDs with high efficiencies.

Thermally activated delayed fluorescence (TADF)
TADF process explained by TD-DFT

TADF is a recent area of intense research as inexpensive organic compounds are exploited as suitable emitters in organic light-emitting diodes (OLEDs) due to high efficiencies made possible by harvesting energy from both singlet and triplet states like in expensive iridium complexes.
