The synthesis of the new aryl bis(β-diketone) ligand m-phenylenebis(acetylacetone) (m-pbaH2) allowed for complexation with copper(II) to form a 4-membered ring Cu4(m-pba)4. An alternate route, via a phospholene adduct, was implemented after difficulties in preparing the ligand via an azo sulfide conversion from m-phenylenediamine. The connection of two m-pba ligands coordinated to a Cu(II) metal ion causes a distortion along the axial position of the metal center. The pore has a diameter of (Cu-----Cu = 14.317 Å) when viewing opposite metal centers. An open coordination site along Cu(II) axial position may facilitate host-guest binding interactions. The concave shape of the host may allow for molecules with a spherical shape such as C60 to favorably interact. UV-Vis spectroscopy monitored the host-guest binding interaction of Cu4(m-pba)4 & C60.
