Complexation of aromatic compounds with self-assembled PdII and PtII metallacycles

• The metal-directed self-assembly of PdII/PtII-metallacycles is described.
• PtII-metallacycles efficiently self-assemble under microwave irradiation.
• The cavity size of the receptor determines the stoichiometry of the complex.
• Stereoselectivity and regioselectivity rely on host–guest complementarity.
• PAHs can be complexed in aqueous media.

Due to their stereoelectronic characteristics and flexible design, 2D self-assembled metallacyclic supramolecules can be considered as optimum potential receptors for aromatic systems. In the present account we focus on our contributions to the field of host–guest chemistry of metallacyclic PdII/PtII-receptors. It will be shown how effective complexation of aromatic substrates, including some of environmental significance, can be achieved by a careful selection of the ligands and metal centers involved in the self-assembly processes.
