Nobody′s perfect: The metal-organic framework Ce(HTCPB) is structurally mismatched to both the para and meta isomers of xylene. It restructures synergically around the para isomer to give a high-quality structural and functional fit, but rearrangement around the meta isomer requires larger host distortions and gives a poorer fit than in the para case. This “off-target” host thus has high selectivity for the sorption of para- over meta-xylene.
