I completed my three-month Master of Research project in the Credgington group (Optoelectronics group) in 2018. I investigated how molecular modifications changed the photophysics of a class of organometallic emitters known as carbene-metal-amides (CMAs). CMAs are a fascinating class of emitter due to the unprecedented speed and efficiency at which they harvest usually dark triplet excitons for light emission. This process occurs through thermally-activated delayed fluorescence and is enhanced due to the spin-orbit coupling afforded by their metal centres. Probing the effect of molecular modifications involved characterising the photophysical properties of the emitters using steady-state and time-resolved experiments. My work from this project features in Chemical Science and Chemistry of Materials.
