Metal-Organic Lumiphores
Learn more about our approaches to novel low-energy emitters, unusual electronic/magnetic structures, and their applications in imaging and therapy here.
Highly Covalent, Radical linkers
Better energetic matching between nodes and linkers should increase tunability of radical core emission in the resulting complexes. While many NIR-emitters are complex organic scaffolds, plagued with C-Hs and poorly tunable, we are developing new synthetic strategies to fine-tune NIR lumiphores and delve deeper into their photophysical origins.
Imaging and Applications
While biological imaging in the NIR has lagged behind due to the scarcity of bright, compatible emitters in that region, the high resolution due to tissue transparency and low energy light make this area of research highly promising. We are developing a range of tunable NIR-I and II emitters for application in both imaging and therapeutics.
Promoting and Assessing Coupling
By inserting an S = 1/2 linker, direct exchange between paramagnetic metal nodes can be realized via coupling to the bridging radical ligand. Simultaneously, fusion of open-shell linkers and metal nodes gives rise to systems with delocalized charge carriers. Studying the synergistic effects of magnetism and charge transport could pave the way to next generation spintronics devices.
