Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Construction</bold> of a self‐assembled cage complex through three different Zn^II centers is achieved using a Zn porphyrin ligand with four 2, 2′‐bipyridin‐5‐yl (bpy) groups. The multiporphyrin cage encapsulates guest molecules unsymmetrically by π–π interactions. Well‐balanced aqueous conditions, which allow the formation of both tris(bpy) and hydrated bis(bpy) Zn^II units, result in the unsymmetrical yet well‐defined supramolecular structure.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1p994hj6" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
