Abstract

A novel sodium complex [Na2(L)2(Phen)2(H2O)2]·2(H2O) (L = 3-hydroxyquinoline-4-carboxylic acid anion; Phen = 1,10-phenanthroline) is synthesized by solvothermal approach and is structurally determined by single-crystal X-ray diffraction. The title complex crystallizes in the orthorhombic system of the Pbcn space group. The strong π⋯π stacking and hydrogen bonding interactions produce three-dimensional (3D) chains. A series of properties of the title complex were tested by solid-state photoluminescence, CIE analysis and solid-state diffuse reflectance. The results show that the title complex is a blue light emitter, CIE (x = 0.1542, y = 0.0211) and has an energy bandwidth of 1.607 eV. A novel sodium complex is synthesized via solvothermal approach, which is characteristic of an isolated structure. At the same time, it displays a narrow and intense photoluminescence emission band in the blue region and has an energy bandwidth of 1.607 eV.
