According to recent research from Sydney, Australia, "An investigation of the interaction of hydroquinone and selected substituted derivatives with the 28-membered tetrabenzo-cyclophane-type receptor 1 and a tetramethoxy-substituted variant, 2, each incorporating an O4N2-heteroatom set, is reported. In a preliminary solution study, aromatic solvent introduced shift (ASIS) experiments had indicated that deuterated benzene is intercalated between the two xylyl bridges of cyclophane 1. In parallel with this result, a further NMR study was consistent with the inclusion of hydroquinone between the xylyl groups of 1 to produce a face-to-face pi-stacked arrangement, with ...
