Work in the Ragogna Group is centred on the chemistry of the main group, p-block elements and usually feature the element phosphorus (P).  We aim to discover unusual structure and bonding in small molecule architectures that then extend to unprecedented reactivity.  Members of the group have a particular focus on P-H bond addition chemistry to element-element multiple bonds (e.g. C=C; C=N) and leverage these reactions to prepare novel linear and crosslinked macromolecular materials with properties to address real world problems. We translate our results to the modification of surfaces to impose them with anti-ice, antimicrobial, superhydrophobic or oxygen scavenging properties. After we develop solution phase, bulk scale syntheses for our functional materials we then endeavour to establish gas phase process so that the same materials can be deposited as thin films, 10-100 nm in thickness.

To accomplish these goals, we have a vibrant, diverse ecosystem of Postdoctoral, PhD, MSc and BSc researchers who work together with our expert technical staff in Western’s core analytical and tooling facilities across campus. Collaborative relationships with other research groups and regular interactions with private sector partners is a common part of our laboratory environment that provides breadth and diversity to research experiences.  The team has many opportunities for tackling relevant ‘real world’ problems by dovetailing their activities with scientists working outside the university setting.
