alkyl-chained organic molecule, 4,5,6,7-tetrachloro-2-dodecylisoindoline-1,3-dione (1), was crystallized into needle-like crystals in dichloromethane (1DCM) or plate-like ones in tetrahydrofuran (1THF) depending on the recrystallisation solvent. X-ray crystallography analyses revealed the alkyl chains of the molecules, in which they were assembled differently, with the former responding flexibly bendable
长烷基链有机分子 4,5,6,7-tetrachlor-2-dodecylisoindoline-1,3-dione ( 1 ) 在二氯甲烷 ( 1 DCM )中结晶成针状晶体或在四氢呋喃 ( 1 THF ) 取决于重结晶溶剂。X射线晶体学分析揭示了分子的烷基链,它们的组装方式不同,前者响应柔性可弯曲和弹性变形,后者在外部机械应力下成为永久性塑料。弹性模量(E)和硬度(H) 表明柔顺和柔软的性质,反映了它们在晶体中的弱相互作用,从纳米压痕测试中量化。
