Abstract:
The coordination chemistry of formazanate ligands with main group and transition metal elements has received significant attention due to the optical and redox properties imparted by this intriguing class of N-donor chelating ligands.1 Our work in this area has focused on the study of structure-property relationships in boron formazanate complexes for the development of novel dye architectures, including examples with relatively simple structures that emit in the near-IR (e.g., 1). We have also prepared emissive polymers via ring-opening metathesis polymerization and studied copolymerization as an approach to boosting emission quantum yields. More recently, we explored the effects of non-traditional bonding (e.g., 2) and cationic charge (e.g., 3) at boron on the optoelectronic properties of this fascinating class of heterocycles with a view of establishing design principles for multifunctional dyes based on main group elements. Our recent progress in the area will be discussed.
