Switching Dielectric Constant Near Room Temperature in a Molecular Crystal

---

Switchable materials have been attracting great attention because of their potential applications as switches, sensors, and memory devices. [ 1–4 ] Upon external stimuli, these materials can show switch-like behaviors between two (or more) states. Taking magnetic materials for example, spin crossover compounds can be switched between high- and low-spin states via spin unparing and paring (e.g., t 2g 4 e g 2 ↔ t 2g 6 e g 0 in Fe(II) complexes)
triggered by temperature, pressure, light, and/or chemicals. [ 3–6 ] As an electrical counterpart, switchable dielectric materials have only recently been identifi ed. [ 7,8 ] They distinguish themselves by undergoing dielectric transitions between high- and low-dielectric states, a switching property that looks like spin
crossover, although the origin arises from atomic or ionic rearrangements rather than the spin pairing and unparing in spin crossover compounds. [ 7–11 ] These types of materials enlarge the family of the widely used dielectric materials and would fi nd potential applications in electrical and electronic industries.
