| Abstract: | The self‐inclusion behavior of monoester copillar5]arenes depends on the position of the ester group, which causes different guest selectivities. Monoester copillar5]arenes bearing an acetate chain can form stable self‐inclusion complexes in low‐ and high‐concentration solution and exhibit high guest selectivity. However, a monoester copillar5]arene bearing a butyrate chain can not form a self‐inclusion complex and exhibits low guest selectivity. Thus, a new class of stable self‐inclusion complexes of copillar5]arenes was explored to improve the selectivity of molecular recognition. |
