Abstract: Boron complexes of N-donor ligands represent a diverse class of molecular materials that have shown utility as sensors, light-harvesting materials, and cell-imaging agents. Given their application, there is an ongoing need for the discovery of new examples that can be produced by straightforward synthetic methods from low cost starting materials. BF2 formazanates, derived from formazans (R1-NH-N=CR3-N=N-R5), are readily accessible heterocycles that exhibit tunable absorption, photoluminescence, and redox properties and potentially address this need. This presentation will highlight our recent work surrounding the chemical functionalization of BF2 formazanates en route to examples that show utility as cell-imaging agents,[1] as precursors to unusual BN heterocycles[2] and -conjugated metallopolymers,[3] and as near-IR photoluminescent dyes.[4],[5]

Bio: Joe Gilroy is an Associate Professor of Chemistry at The University of Western Ontario. He completed his BSc and PhD at the University of Victoria where he conducted research in stable radical chemistry under the supervision of Prof. Robin Hicks. He moved to the University of Bristol for his postdoctoral studies where he worked in various areas of metallopolymer chemistry with Prof. Ian Manners as an NSERC and EU Marie Curie PDF. At Western, Joe leads a talented team of students and postdocs, with major focuses including the development of luminescent and semiconducting molecular and polymeric materials. He has received several awards, including the Thieme Chemistry Journal Award, Western's Petro-Canada Young Innovator and Faculty Scholar Awards, and the CNC-IUPAC travel award.
