The approach for enhancing the elasticity of crystals with suboptimal elastic performances through a rational design was presented. A hydrogen-bonding link was identified as a critical feature in the structure of the parent material, the Cd(II) coordination polymer [CdI(I-pz)] (I-pz = iodopyrazine), to determine the mechanical output and was modified via cocrystallization. Small organic coformers resembling the initial organic ligand but with readily available hydrogens were selected to improve the identified link, and the extent of strengthening the critical link was in an excellent correlation with the delivered enhancement of elastic flexibility materials.
本文提出了一种通过合理设计来提高弹性性能欠佳的晶体弹性的方法。氢键连接被确定为母体材料Cd(II)配位聚合物[CdI(I-pz)]（I-pz = 碘吡嗪）结构中的一个关键特征，用于确定机械输出，并通过共结晶进行修饰。选择与初始有机配体相似但带有易于获取氢原子的小有机共形成物来改善所确定的连接，并且关键连接的强化程度与弹性柔韧性材料所实现的增强效果具有极佳的相关性。
