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
拧紧到位:当双链体围绕客体缠绕时,一种反平行的双螺旋芳族低酰胺折叠剂显示与一系列不同长度的棒状客体结合(请参见方案)。主客体复合物的固态晶体结构表明,双链体的两条链经历相对的螺旋运动,以调节位于其末端之一末端的氢键供体之间的距离,从而使它们与氢键结合客人的接受者。
