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…
