Dale, Edward J.; Ferris, Daniel P.; Vermeulen, Nicolaas A.; Henkelis, James J.; Popovs, Ilja; Juríček, Michal; Barnes, Jonathan C.; Schneebeli, Severin T.; Stoddart, J. Fraser;

A tetracationic pyridinium-based cyclophane with a box-like geometry, incorporating two juxtaposed alkyne functions, has been synthesized. The triple bonds are reactive through cycloadditions toward dienes and azides, promoted by the electron-withdrawing nat... View more
