Our project aims to unravel the dynamics of single spin crossover complexes using nanoscale quantum sensing. Single molecular spins will be probed using NV centers in diamond. We will address the heterogeneity of complexes and the influence of the local environment on spin dynamics at the single molecule level. We expect that the technique based on quantum sensing will not only allow to reach ultimate sensitivity, but also to detect spins with short coherence time not visible in conventional magnetic resonance.
