Abstract

A series of novel copillar[5]arenes 1a1f containing different substituents were synthesized. And their complexation with two types of guests was investigated. For symmetrical guests, 1,4-dibromobutane (DBB) could thread in the cavity of copillar[5]arenes to form inclusion complexes. But for the unsymmetrical guests, copillar[5]arene 1f bearing 4-(naphthalen-1-yloxy)butoxy could not complex with sec-butyl iodide (SBI) and sec-butyl bromide (SBB) at all, while 1f showed weak interaction with sec-butylamine·HCl (SBA) outside the cavity. These results indicated that the modified group of copillar[5]arene and the symmetry of guest played an important role in the complexation model and selectivity.
