A novel luminescent Lead coordination framework with quinoline-6-carboxylic acid

A novel photoluminescent coordination framework Pb(qlc)2 (Hqlc = quinoline-6-carboxylic acid) (1), has been obtained through self-assembly of Pb(NO3)2 with Hqlc ligand and characterized by IR spectra and elemental analysis. Single-crystal X-ray diffraction analysis reveals that the complex adopts a (4,4) topological layer structure. Solid state emission spectrum of the compound exhibits blue-violet luminescence upon exposure to ultraviolet radiation.
