Controlling molecular conformation through macroscopic mechanical stimulus may have applications in chiroptical devices, but achieving this in a 3D material is challenging. Now, a quantitative relationship between stretching of an elastomer and reversible conformational changes of a crosslinked molecule has been established.

分子构象的可逆机械控制

通过宏观机械刺激控制分子构象可能在手性光学器件中有应用，但在 3D 材料中实现这一点具有挑战性。现在，已经建立了弹性体的拉伸与交联分子的可逆构象变化之间的定量关系。
