Abstract

Coordination-driven self-assembly of nickel (II) ions with equimolar amounts of 1, 10 phenanthroline, and benzoic acid was used to create homonuclear nickel (II) MOF-type supramolecule. Single crystal X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, photoluminescence measurement, FT-IR, UV-visible spectroscopy, and nitrogen physisorption measurement were used to characterize the compound. The single crystal X-ray diffraction study reveals that the synthesized compound is two-dimensional with pores in the structure. The homonuclear nickel (II) MOF-type supramolecule crystallized in a triclinic crystal system, with space group P-1 (No.2) and unit cell parameters a = 9.2053(4) Ǻ, b = 13.2964(5) Ǻ, c = 15.8998(6) Ǻ, α = 66.296(2) °, β = 89.400(2) °, γ = 89.441(2) °. The crystal structure result shows ?- ? and intermolecular interactions between adjacent 1, 10-phenanthroline molecules. DSC result showed a gradual decomposition confirming thermal stability of the compound. The emission (468 nm) spectrum result shows energy peaks of a typical multiphonon phase, indicating luminescence process. The surface topology and single absorption maximum at 308 nm reveal formation of a distorted octahedral structure. Brunauer?Emmett?Teller and Langmuir surface area results 383.741 and 975.830 m2g?1, respectively, indicate high adsorption capacity. Langmuir isotherm model result of the compound shows an efficient adsorption property for storing energy. The excellent nickel (II) MOF-type supramolecule adsorption capacity and emission property opened the door to its use in energy storage applications especially in photovoltaic cells.
