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 [CdI₂(I-pz)₂]_n (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.

定制增强的结晶配位聚合物的弹性

提出了通过合理设计增强弹性性能次优晶体弹性的方法。氢键连接被确定为母体材料 Cd(II) 配位聚合物 [CdI ₂ (I-pz) ₂ ] _n (I-pz = iodopyrazine) 结构中的一个关键特征，以确定机械输出并通过共结晶进行了修改。选择类似于初始有机配体但具有容易获得的氢的小型有机共形成剂来改进已识别的链接，并且加强关键链接的程度与弹性柔韧性材料的传递增强具有极好的相关性。
