generation of large numbers of self-assembled molecular capsules from relatively few reversibly associating components. This library of capsules displays spontaneous selection of the strongest receptors for the binding of guest molecules. Molecular capsules emerge when subunits displaying appropriate curvature and self-complementary hydrogen bonding sites selfassemble. 3 These capsules assemble only in the presence

Pendant methoxyl groups are essential for the assembly process and convey their influence through both electronic pathways and surface interactions. Spin polarization transfer experiments show that the capsule undergoes rapid guest-exchange processes while being itself kinetically stable at elevated temperatures.
