Synthesis and Application of New Host Molecules derived from Macrocycles.

1.成功地合成了双臂冠醚。它们对银离子表现出较高的离子选择性。还与环糊精在水中通过光环加成反应合成了含氨基的冠醚。通过与冠醚的离子-偶极相互作用，成功地合成了含[2]-和[3]的链烷。用两种不同的方法研究了[60]富勒烯双加合物的产物分布。Benzyne方法只给出了顺式-1形式。所有的外消旋体(反式-2、反式-3和顺式-3)都通过手性高效液相色谱柱层析成功地拆分成每个对映体。冠醚结构的双加合物对碱金属离子表现出独特的离子选择性。成功地合成了具有一定乙酸乙酯单元的杯芳烃。它们对碱金属离子具有良好的萃取性。随着乙酸乙酯单元数目的减少，对Rb、Cs等较大离子的萃取率逐渐降低。它们在氨基醇的作用下成功地转化为树枝状大分子。

1. Double armed crownophanes were successfully synthesized. They showed the high ion selectivity for silver ion. Crownophanes containing amino group were also synthesized with cyclodextrin in water by photocycloaddition. Catenanes including[2]- and [3] catenanes were successfully synthesized by using ion-dipole interaction with crownether.2. The product distribution of [60]fullerene bisadducts was investigated by the different two methods. The benzyne method exclusively gave cis-1 form. All racemates (trans-2, trans-3, and cis-3) were successfully resolved into each enantiomer by using chiral HPLC column chromatography. Bisadducts attaching crownether moiety showed the unique ion selectivity for alkali metalions.3. Calixarenes having some ethyl acetate units were successfully synthesized. They showed the good extractability for alkali metal ions. When the number of the ethylacetate unit decreased, the extractability for larger ions like Rb^+ and Cs^+ gradually decreased. They were successfully converted to dendrimer type molecules with amino alcohol.
