Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A M₂L₂ rectangular‐shaped metallacycle, obtained by metal‐directed self‐assembly of a 2‐(pyridin‐4‐ylmethyl)‐2, 7‐diazapyrenium salt and [(en)Pd (NO₃)₂] (en=ethylenediamine), has been investigated as a molecular receptor for a wide range of aromatic substrates in water. Complexation and catenation of the receptor with selected mono‐ and polycyclic aromatic substrates produced 1:1 inclusion complexes and [2]catenanes in a highly efficient fashion, as determined by NMR and UV/Vis spectroscopic techniques, as well as single‐crystal X‐ray crystallography. Furthermore, the thermodynamic and kinetic features of the complexation processes have been analyzed for selected model guests.</p> </abstract>
