摘要：

Two new self-complementary molecules are described which are capable of assembling into dimeric capsules. The size and shape of the cavity follow previous designs, but peripheral functional groups permit enhanced solubility. Binding of CH4, H2C=CH2, and xenon within the capsules is demonstrated. Peripheral basic sites on one of the capsules permit the control of assembly by protonation/deprotonation reactions. The encapsulation of xenon is demonstrated for the more organic soluble capsule by proton and xenon nuclear magnetic resonance spectroscopy.
