| Abstract |
CuX(melamine) (X = Br and I), a new organic-inorganic hybrid material, were synthesized as single crystals via hydrothermal method. Their crystal structures were determined by single crystal X-ray diffraction and all compounds show triclinic symmetry (space group = P -1). In these structures, copper halides exhibit 1-dimensional stair step polymer structure built up by two chains including copper atom and halogen atom. Three halogen atoms are coordinated to copper atom and each melamine ligand affords one N-heterocycle N atom as the forth coordination of Cu. Abundant hydrogen bonds of melamine stabilize the crystal structure by connecting inter and intralayer. Photoluminescence properties of CuBrxI1-x(melamine) were investigated according to halogen atom ratio. When excited at about 300 nm, the maximum emission wavelengths in the photoluminescence spectra were varied on the compositional ratio of halides : e. g. blue for x = 0, white for x = 0.5 and green for x = 1. |
