Monoester copillar[5]arenes: synthesis, unusual self-inclusion behavior, and molecular recognition.
The self-inclusion behavior of monoester copillar[5]arenes depends on the position of the ester group, which causes different guest selectivities. Monoester copillar[5]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 copillar[5]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 copillar[5]arenes was explored to improve the selectivity of molecular recognition.
A monophosphoryl copillar[5]arene: synthesis and host–guest complexation with alkanols
A monophosphoryl copillar[5]arene 1 was prepared. The introduction of the phosphoryl group remarkably promoted the binding affinity of 1 with alkanols and alkanediols in comparison with 1,4-dimethoxypillar[5]arene. Thus 1 can form a stable 1 : 1 host–guest complex with alkanols in CDCl3.
