Research Seminar-

Metal complexes are promising candidates for spin applications spanning from magnetic resonance imaging to quantum information processing. A key challenge in advancing these applications is fundamentally understanding how to generate long spin relaxation times (T1, T2) in magnetic environments. A major contributor to this challenge is the presence of other magnetic nuclei in the environment which is known to cause the shortening of spin relaxation. Current research reduces or eliminates the presence of other nuclei. Although this has shown to lengthen relaxation the aforementioned applications will have nuclei present. We aim to understand how specific modifications of nuclear spins, and other environmental factors, impact electron spin relaxation times to design metal complexes with long relaxation times in highly magnetic environments. A series of Vanadium(IV) triscatecholate complexes were investigated at high field/high frequency electron paramagnetic resonance to understand how modifications to the nuclear spins and counterions affect the V(IV) electron spin relaxation.
