Syntheses, structures, and photo-luminescence of three silver complexes with N-heterocyclic multicarboxylic acids and 4,4 '-bipyridine 作者:Qu, J (Qu, Jing)[ 1 ] ; Yi, YL (Yi, Yong-Ling)[ 1 ] ; Hu, YM (Hu, Yao-Min)[ 1 ] ; Chen, WT (Chen, Wei-Tao)[ 1 ] ; Gao, HL (Gao, Hong-Ling)[ 1 ] ; Cui, JZ (Cui, Jian-Zhong)[ 1 ] ; Zhai, B (Zhai, Bin)[ 2 ] JOURNAL OF COORDINATION CHEMISTRY 卷: 65 期: 21 页: 3740-3751 DOI: 10.1080/00958972.2012.724530 出版年: 2012 文献类型:Article 查看期刊影响力 摘要 Three coordination polymers, [Ag-4(bpy)(3)(pztc)](n) (1), {[Ag-6(bpy)(2)(pztc)(CN)(2)] center dot 2.6H(2)O}(n) (2), and {[Ag-2(H(2)pdtc)(bpy)(2)] center dot 3H(2)O}(n) (3) (H(4)pztc = pyrazine-2,3,5,6-tetracarboxylic acid, H(4)pdtc = pyridine-2,3,5,6-tetracarboxylic acid, bpy = 4,4'-bipyridine), have been synthesized and characterized by elemental analysis, IR spectra, thermogravimetric analysis, UV spectra, fluorescent spectra, and single-crystal X-ray diffraction. Complex 1 displays a 3-D network with infinite channels of about 6.4 x 3.1 angstrom(2) along the a-axis. The structure of 1 can be simplified as a 3,4,4-connected framework. Complex 2 displays a 3-D network and can be simplified as a 6,6-connected pcu framework. Complex 3 shows a 1-D chain structure and the chains form a 2-D layer structure by hydrogen bonds. Complexes 1-3 emit intense fluorescence at around 500nm on excitation at 340 nm, 320 nm, and 340 nm, respectively. 关键词 作者关键词:Silver(I) complex; Pyrazine-2,3,5,6-tetracarboxylic acid; Pyridine-2,3,5,6-tetracarboxylic acid; Fluorescent properties KeyWords Plus:COORDINATION POLYMERS; CRYSTAL-STRUCTURE; SUPRAMOLECULAR INTERACTIONS; LIGAND; LUMINESCENCE; COMBINATION; BONDS 作者信息 通讯作者地址: Cui, JZ (通讯作者) 显示更多 Tianjin Univ, Dept Chem, Tianjin 300072, Peoples R China. 地址: 显示更多 [ 1 ] Tianjin Univ, Dept Chem, Tianjin 300072, Peoples R China 显示更多 [ 2 ] Shangqiu Normal Univ, Coll Chem & Chem Engn, Shangqiu 476000, Henan, Peoples R China 电子邮件地址:cuijianzhong@tju.edu.cn 基金资助致谢 基金资助机构 授权号 National Natural Science Foundation of China 21001078 21 001 071 21271137 Key Laboratory of Advanced Energy Material Chemistry (Nankai University) KLAEMC-OP201101 查看基金资助信息 出版商 TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND 类别 / 分类 研究方向:Chemistry Web of Science 类别:Chemistry, Inorganic & Nuclear 文献信息 语言:English 入藏号: WOS:000309128800005 ISSN: 0095-8972 eISSN: 1029-0389 其他信息 IDS 号: 010XW Web of Science 核心合集中的 "引用的参考文献": 39 Web of Science 核心合集中的 "被引频次": 9 |
