摘要: 以均苯四甲酸二酰亚胺和1,5-萘二酚为基本结构单元,设计合成了一种不对称的37-冠-10 (1), 解析了其晶体结构,进而采用紫外和核磁等手段研究了其与一些阳离子的键合行为. 结果表明,冠醚1存在分子内的电荷转移相互作用,导致的较小空腔对锂离子表现出较强的键合能力.

Abstract: A new asymmetric 37-crown-10 (1) with a pyromellitic diimide unit and a 1,5-naphthalene unit was synthesized, and its structure was resolved by X-ray diffraction. The binding behaviors of 1 with some cations were investigated by UV and 1H NMR spectroscopies. The crystal structure obtained shows that there are two smaller cavities due to the strong interaction from the intramolecular charge transfer. The structural feature is beneficial to the complexation of 1 with smaller cations. The UV experiments show that its binding ability for lithium is the strongest, that for sodium is weak, and no binding for other akali metal or alkaline-earth metal ions.
