<i>C</i>-Pentyltetra(3-pyridyl)cavitand: A Versatile Building Block for the Directed Assembly of Hydrogen-Bonded Heterodimeric Capsules

Hydrogen-bond-directed assembly of heterodimeric cavitand-based capsules is of considerable interest. Herein, we report the synthesis and single-crystal X-ray structure determination of a pyridyl-functionalized cavitand that contains suitable hydrogen-bond acceptor moieties for the construction of asymmetric cavitand-based capsules.
