摘要：

Screwed in place: An anti-parallel double-helical aromatic oligoamide foldamer was shown to bind to a series of rodlike guests of various lengths upon the winding of the duplex around the guests (see scheme). Solid-state crystal structures of the host-guest complexes show that the two strands of the duplex undergo a relative screw motion to adjust the distance between hydrogen-bond donors located at the end of one of their extremities so that they bind to hydrogen-bond acceptors of the guest.
