Dynamic organic crystals have come to the fore as potential lightweight alternatives to inorganic actuators providing high weight-to-force ratios. We have observed pressure-induced superelastic behaviour in Form I of isonicotinamide. The reversible single-crystal to single-crystal transformation exhibited by the system is an important component for functioning actuators. Crucially, our observations have enabled us to propose a mechanism for the molecular movement supported by Pixel energy calculations, that may pave the way for the future design and development of functioning dynamic crystals.

异烟酰胺的压力诱导超弹性行为

动态有机晶体已成为无机致动器的潜在轻质替代品，可提供高重量与力的比率。我们已经观察到异烟酰胺 I 型的压力诱导超弹性行为。该系统表现出的可逆单晶向单晶转变是功能致动器的重要组成部分。至关重要的是，我们的观察使我们能够提出一种由像素能量计算支持的分子运动机制，这可能为未来功能性动态晶体的设计和开发铺平道路。
