Abstract

Dynamic cavity is widespread in living matter and supramolecular scaffolds. Generally speaking, flexible building block as a segment is used to realize dynamic cavities building in artificial molecules and materials. However, the incorporation of rigid synthetic supramolecular scaffolds with flexible cavity motion remains rare. Inspired by rotational origami patterns, giant shape amphiphile (GSA), POSS-NDI-POSS (PNP), assembled into an origami nano-box with feature of rotational expansion. The open/close of cavity and size control of PNP host can be adjusted by rotational offset between adjacent PNP in supramolecule entities. The rotational offset of 150°, 130° and 0° were observed when the host nano-box presented close, half-open and fully-open state, respectively. The rotational expansion of PNP trigged by gaseous arenes makes PNP as a novel nonporous crystal. Compared with conformation change in flexible building segment, rotational expansion in acyclic host (PNP) provides a new strategy for the development of rigid segment to build adaptive host-guest recognition.

巨型双亲化合物制成的可扩展旋转折纸纳米盒

动态空腔广泛存在于生命物质和超分子支架中。一般来说，人造分子和材料中的动态空腔构建都是以柔性构件为片段来实现的。然而，将刚性合成超分子支架与柔性空腔运动结合在一起的情况仍然很少见。受旋转折纸图案的启发，巨型双亲化合物（GSA）、POSS-NDI-POSS（PNP）组装成了具有旋转扩展功能的折纸纳米盒。超分子实体中相邻 PNP 之间的旋转偏移可调节空腔的开闭和 PNP 主控体的大小。当主纳米盒呈现关闭、半开和全开状态时，旋转偏移分别为 150°、130° 和 0°。气态烯引发的 PNP 旋转扩展使 PNP 成为一种新型无孔晶体。与柔性结构段的构象变化相比，无环宿主（PNP）的旋转扩展为刚性结构段的发展提供了一种新策略，以建立适应性的宿主-访客识别。
