合成了六元瓜环与链状烷基二胺(1,2-乙二胺)形成的超分子化合物.采用X射线衍射技术测定了其晶体结构,并得到元素分析、热重、红外光谱的佐证,揭示了主客体相互作用的模式.还采用1HNMR技术研究了溶液中六元瓜环与乙二胺的超分子相互作用.研究表明,在不同的环境下瓜环与客体采取相异的超分子作用模式,晶体结构中显示一个六元瓜环的两个端口通过离子偶极作用以不同的作用模式分别跟两个乙二胺客体分子形成一个三单元组成的超分子作用实体;而在溶液中瓜环与乙二胺的相互作用模式与晶体中的不同.
Supramolecular compounds formed by a six-membered guaiacol ring and a chain alkyldiamine (ethylenediamine) were synthesized.The crystal structure was determined by X-ray diffractometry and analyzed by elemental analysis, TG-IR and The interaction between host and guest was revealed by 1HNMR and the supramolecular interaction between the six-membered ring and ethylenediamine was also studied by 1HNMR.The results show that in different environments, Molecular mode of action, the crystal structure shows a six-membered melon ring of the two ports by ion dipole interaction in different modes of action with two ethylenediamine guest molecules to form a three-member supramolecular entity; and in solution Meloid ring and ethylenediamine interaction mode and crystal different.
