Synthesis and Application of New Host Molecules derived from Macrocycles.

1.成功地合成了双臂冠芳。它们对银离子具有很高的选择性。在水溶液中，环糊精与冠醚通过光环加成反应合成了含氨基的冠醚。利用冠醚与离子偶极相互作用，成功地合成了[2]-和[3]-链状化合物.用这两种方法研究了[60]富勒烯双加合物的产物分布。苯炔法仅得到顺式-1形式。通过使用手性HPLC柱色谱法，所有外消旋体（反式-2、反式-3和顺式-3）成功地拆分成每种对映异构体。冠醚双加成物对碱金属离子表现出独特的离子选择性.合成了含有乙酸乙酯单元的杯芳烃。它们对碱金属离子表现出良好的萃取性能。当乙酸乙酯单元的数量减少时，对较大离子如Rb^+和Cs^+的萃取能力逐渐降低。用氨基醇将它们成功地转化为树枝状分子。

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.
