Morphology-selective formation and morphology-dependent gas-adsorption properties of coordination polymer particles

The selective formation of coordination polymer particles (CPPs) with diverse shapes from the same basic building blocks namely elongated hexagons, ellipsoids, and rods, was reported. A carbonyl-functionalized ligand was synthesized with slight changes. CPPs were prepared by the solvothermal reactions, where H₂L, In(NO₃)₃. xH ₂O, imidazole, and CH₃CO₂H were combined in dimethylformamide (DMF). The morphology of the resulting product was characterized by field-emission Scanning Electron microscopy (SEM), Optical Microscopy (OM), and Fluorescence Microscopy (FM). The images reveal the formation of elongated hexagonal particles, with an average width and length of 1.52 and 3.00μm. It was also observed that the diversely-shaped CPPs have different gas-adsorption properties for several gas molecules, even though they have the same components.
