Remarkable impact of KBr pelletization on spin switching: probing Hofmann-type 3D spin-crossover frameworks by solid-state optical spectroscopy
KBr pelletization profoundly influences the thermal and photoinduced spin-crossover behavior in dehydrated [Fe<sub>1-<i>x</i></sub>M<sub><i>x</i></sub>(pz)Pd(CN)<sub>4</sub>] in bulk, nanoparticles and polymer composite forms by inducing tensile strain, defects, dopant-rattling, and electrostatic perturbations that alter Δ<i>E</i>0HL and cooperativity. It enables hidden thermal switching, dopant dynamics, and quantum-tunneling-driven LIESST relaxation, revealing mechanical processing as a versatile tool to tune spin-state energetics and cooperativity.
