Tunable Bistability in a Three‐Dimensional Spin‐Crossover Sensory‐ and Memory‐Functional Material

Abstract

Spin-crossover (SCO) complexes based on three-dimensional coordination polymers (see Figure) exhibit unprecedented pressure-tunable thermal and piezochromic bistability at room temperature. The thermal- and piezohysteresis loops of the material can be tuned, providing a step towards reliable pressure-based memory systems or displays.
