Exploring the adsorption and separation of water, methanol, and ethanol is important concerning the use of a sustainable energy source from biofuel. In this paper, the effects of the flexibility of substituted groups have been studied based on three iso-reticular metal–organicframeworks (MOFs), in which the pore surface is decorated with propargyl (–CH2–CCH), allyl (–CH2–CHCH2), and propyl (–CH2–CH2–CH3)
Few‐layers thick metal‐organic nanosheets have been synthesized using water‐assisted solid‐state transformation through a combined top‐down and bottom‐up approach. The metal‐organicpolyhedra (MOPs) convert into metal‐organic frameworks (MOFs) which subsequently self‐exfoliate into few‐layered metal‐organic nanosheets. These MOP crystals experience a hydrophobicity gradient with the inner surface during

ne (bpp) ligand. Topology analysis indicated that compound 1 showed a 3D lvt topology, whereas compound 2 showed a two-fold interpenetrated 3D diamond network. Complexes 3 and 4 exhibited 2D sql/Shubnikov tetragonal plane networks. The coordination polymers were distinguished by the 5-substituted groups of isophthalate and the conformation of bpp. Moreover, compounds 2–4 are bifunctional luminescent

that substitutions of isophthalic acid ligands with different lengths exert significant effects on the architecture of the CPs. Besides, the fluorescent properties of 1–6 were also investigated. The magnetic measurements indicate that CP 7 exhibits weak antiferromagnetic interactions, and CPs 8–10 exhibit weak ferromagnetic interactions within the binuclear (CoII)2 units.
