Magnetic molecules are critical components in current and next generation applications in magnetic resonance imaging and quantum information processing. Toward functionality in these applications, long spin-lattice relaxation (T1) and spin-spin relaxation (T2) times are desired. However, there is a fundamental challenge here – most magnetic molecules display short T1 and T2 values when in the presence of a magnetic environment (the spin bath). Bioimaging environments and information storage environments are spin-rich. Hence, to move toward application of magnetic molecules for these applications, we need to understand how to design long relaxation times in highly magnetic environments. This presentation will detail our efforts to understand the spin-bath to molecule interaction via molecular chemistry. Specifically, we will discuss the response of the relaxation times in magnetic complexes to specific magnetic environments. In the long term, these fundamental studies will provide molecules with long relaxation times in chaotically magnetic environments.
