Spin-State Dependent Pressure Responsiveness of Fe(II)-based Triazolate Metal-Organic Frameworks Fe(II)-containing Metal-Organic Frameworks (MOFs) that exhibit temperature-induced spin-crossover (SCO) are candidate materials in the field of sensing, barocalorics, and data storage. Their responsiveness towards pressure is therefore of practical importance and is related to their longevity and processibility. The impact of Fe(II) spin-state on the pressure responsiveness of MOFs is yet unexplored.
