Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The shortest possible C₇₀ peapods</bold> were formed in a size‐ and orientation‐selective manner from C₇₀ and either [10]cycloparaphenylene (CPP) or [11]CPP as 1:1 complexes. C₇₀ exists in two distinct orientations inside the CPP cavity, namely "lying" and "standing", depending on the size of the CPP. The interaction between [10]CPP and the short axis of C₇₀ is isotropic, but that between [11]CPP and C₇₀ is anisotropic, involving the radial deformation of [11]CPP to an ellipsoidal shape. This "induced‐fit" occurred due to the radically elastic character of the CPPs and maximized the van der Waals interactions with the long axis of C₇₀. For more details, see the Full Paper by S.
