摘要：

(Figure Presented) Hyperextension: A hydrogen-bonded, dimeric capsule can be expanded with four, eight, or twelve glycoluril spacers (see picture) that increase the cavity's volume by up to 530 Å3 and its length by up to 21 Å. The extended assemblies are chiral and encapsulate a variety of normal alkanes. The expanded capsules suggest that increasingly complex capsules may emerge from other spacers with hydrogen-bonding capabilities and curved surfaces. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
