以1H核磁共振技术和X射线单晶衍射分析方法考察了 3种瓜环与长链二胺 ( 1,7 庚二胺与 1,8 辛二胺 )相互作用的结构特征 .1HNMR分析表明瓜环 (Q[6]和Q[7] )与有机二胺 ( 1,7 庚二胺与 1,8 辛二胺 )有较强的相互作用 ,形成自组装类轮烷结构 ;Q[8]与 1,7 庚二胺与 1,8 辛二胺之间相互作用力相对较弱 ;晶体结构测定结果表明 ,六元瓜环与辛二胺自组装形成的类轮烷实体中 ,辛二胺是以直链状穿过六元瓜环的空腔 ,两配位氨基留在瓜环两端口之外 .
1H NMR and X-ray single crystal diffraction methods were used to investigate the structural characteristics of the interaction between the three guanosines and the long-chain diamines (1,7-heptylenediamine and 1,8-octanediamine) .1HNMR analysis showed that guanidine (Q [6] and Q [7]) and organic diamines (1,7heptanediamine and 1,8-octanediamine) have a strong interaction to form a self-assembled disubstituted rotaxane structure; Q [8] 1,7 heptanediamine and 1,8-octanediamine relatively weak interaction force; the crystal structure determination results show that six yuan Gua ring and octanediamine self-assembly of the formation of the class of rotaxane, the octanediamine is In a straight chain through the cavity of the six yuan melon ring, the two ligand amino remain in the melon ring outside the two ports.
