Focus of the figure : A 3D supramolecular architecture, built up through the assembly of a double‐layered 2D honeycomb‐like MOFs, exhibits a stepwise water vapor ad‐/de‐sorption isotherm with the maximum sorption of approximate 4.0 n/mol mol ‐1 H 2 O molecules, which is attributed to structural transformation on the basis of the hydrogen‐bonding affinity of water molecules with the two free N atoms of tcm ‐1 ligand in the framework and the framework flexibility assembled by two‐fold interpenetrated 2D nets. More details about this figure will be discussed by Dr. Chih‐Chieh Wang and his co‐workers on pages 1464‐1472 in this issue. image
