Two new coordination polymers [Cd（EBLA）（ip）（H2O）] （1） and [Ni（EBSA） （im）2（H2O）], （2） were synthesized by hydrothermal and solution methods using 2,2＇-dithio- salicylicacid （EBSA）, lH-imidazo[4,5-f][...Two new coordination polymers [Cd（EBLA）（ip）（H2O）] （1） and [Ni（EBSA） （im）2（H2O）], （2） were synthesized by hydrothermal and solution methods using 2,2＇-dithio- salicylicacid （EBSA）, lH-imidazo[4,5-f][1,10]phenanthroline （ip）, imidazole （im）, Cd（NO3）2-4H2O and Ni（NOa）z＇6H20. The complexes were characterized by elemental analysis and FT-IR. Meanwhile, the crystal structures, fluorescence properties of complex 1 and thermogravimetrie analysis of complex 2 have been studied. In complex 1, 2,2＇-dicarboxydiphenylthioether （EBLA） was prepared with 2,2＇-dithiosalicylicacid （EBSA） in situ reaction by hydrothermal method. Complex 1 is a dinuclear structure and Cd2＋ is five-coordinated in a distorted trigonal bipyramidal geometry. Complex 2 is a one-dimensional infinite linear chain and Ni2＋ is six-coordinated to form a distorted octahedral geometry. Hydrogen bonding and π-π interactions are observed in these complexes.展开更多
One-dimensional cerium phosphate （CePO4） nanorods were successfully synthesized by a facile and simple solvothermal method at 150℃ for 12 h, using Ce（NO_3）_3·6H_20 and NaH_2PO_4·2H2O as the starting mat...One-dimensional cerium phosphate （CePO4） nanorods were successfully synthesized by a facile and simple solvothermal method at 150℃ for 12 h, using Ce（NO_3）_3·6H_20 and NaH_2PO_4·2H2O as the starting materials. Phase and morphologie of the as-synthesized CePO4 products, characterized by XRD, FESEM, and TEM, were proved to be perfect and uniform hexagonal CePO_4 nanorods with aspect ratio of more than 100. The photoluminescence （PL） spectrometer was used to investigate the optical properties of the as- synthesized hexagonal CePO_4 nanorods.展开更多
