structure with a dihedral angle between two planes of quinoline rings as 60.08° and self-assembles with the aid of hydoxy groups and nitrogen atoms in the quinoline rings along with C–H···O interactions. The helical self-assembly of bis-5,5′-[2-(quinolin-8-ylamino)ethanol] can encapsulate guests of two different shapes, namely trigonal planar (nitrate) and tetrahedral (perchlorate), without significantly
为了理解阴离子在螺旋自组装折叠中的堆积,一种新的有机螺旋5,5'-联喹啉衍生物bis-5,5'-[2-(喹啉-8-基氨基)乙醇] ,通过锰(II)催化的CC键形成反应合成具有通过柔性亚乙基键连接的羟基侧基的化合物。该化合物采用螺旋结构,喹啉环的两个平面之间的二面角为60.08°,并借助羟基和喹啉环中的氮原子以及C–H··O相互作用自组装。bis-5,5'-[2-(quinolin-8-ylamino)ethanol]的螺旋自组装可以封装两种不同形状的客体,即三角形平面(硝酸盐)和四面体(高氯酸盐),而不会明显丢失其原始形状螺旋度。发现该螺旋分子与高氯酸和硝酸的相互作用在溶液中是相似的。但是,固态的高氯酸会形成盐,而硝酸会与其形成共晶。
