A new material concept of soft crystals is proposed. Soft crystals respond to gentle stimuli such as vapor exposure and rubbing but maintain their structural order and exhibit remarkable visual changes in their shape, color, and luminescence. Various interesting examples of soft crystals are introduced in the article. By exploring the interesting formation and phase-transition phenomena of soft crystals through interdisciplinary collaboration, new materials having both the characteristics of ordered hard crystals and those of flexible soft matter are expected.
提出了软晶体的新材料概念。软晶体对蒸气暴露和摩擦等温和刺激作出响应，但保持其结构有序，并在形状、颜色和发光方面表现出显著的视觉变化。文章介绍了各种有趣的软晶体实例。通过跨学科合作探索软晶体有趣的形成和相变现象，有望获得同时具有有序硬晶体和柔性软物质特征的新材料。
