Abstract
Described are assemblies consisting of polymeric capsules, ''polycaps, '' formed from two calix[4]arene tetraureas covalently connected at th eir lower rims. In these structures self-assembly leads to reversibly formed capsule sites along a chain, reminiscent of beads on a string. Their dynamic behavior is characterized by H-1 NMR spectroscopy throug h encapsulation of guest species, reversible polymerization, and the f ormation of sharply defined hybrid capsules.
