We acknowledge and pay respect to the Gadigal people of the Eora Nation, the Traditional Owners of the land on which we research, teach and collaborate at the University of Sydney. We acknowledge the supportive environment that the School of Chemistry provides for this work, and in particular P. Devi and the First Year Technical Team for their assistance with trial experiments. Our work has been supported by grants from the Royal Society of Chemistry’s Inclusion and Diversity Fund, the University of Sydney’s Educational Innovation Program and the School of Chemistry’s Alan Williams Bequest.
