A charge-transfer (CT) interaction stabilizes molecular assemblies and can form a useful supramolecular synthon in crystal engineering. Herein we demonstrate preparation of a chiral single crystal showing twinning-based organosuperelasticity by forming a CT complex of an achiral donor–acceptor type Schiff base: N-(2,3,4,5,6-pentafluorophenyl)-1-phenylmethanimine. Pseudo-180° symmetry of a single-component CT complex originating from an antiparallel molecular assembly is the key to mechanical twinning. The chiral crystallization induced by CT interactions is also noteworthy because of the potential development of materials showing CT-based functions coupled with chirality.

基于孪生的电荷转移相互作用诱导的非手性供体-受体型席夫碱单晶的有机超弹性和手性

电荷转移（CT）相互作用可稳定分子组装，并可在晶体工程中形成有用的超分子合成子。在本文中，我们通过形成非手性供体-受体型席夫碱的CT复合物：N-（2,3,4,5,6-五氟苯基）-1-苯基甲胺，展示了显示基于孪晶的有机超弹性的手性单晶。源自反平行分子组装的单组分CT络合物的伪180°对称性是机械孪生的关键。由CT相互作用诱导的手性结晶也是值得注意的，这是因为显示基于CT的功能和手性的材料的潜在发展。
