Synthesis and Crystal Structure of a New Zn(Ⅱ) Complex Exhibiting Strong Luminescence 总被引:1,自引:1,他引:0
The title complex,[Zn(ip)2(H2O)2][ZnCl4]·H2O·2DMF 1(ip=imidazo[4,5-f][1,10] phenanthroline),has been synthesized via the slow evaporation of concentrated reaction solution at room temperature.It was characterized by single-crystal X-ray diffraction.Crystal data for C32H36Cl4N10O5Zn2:white prism,0.17mm×0.15mm×0.10mm,monoclinic,space group P2/c,a=11.928(8),b=9.868(6),c=16.520(11),β=104.879(12)°,V=1879(2)3,Z=2,Mr=913.25,Dc=1.614 g/cm3,F(000)=932,μ=1.616 mm-1,λ(MoKα)=0.71073,GOOF=1.045,R=0.0710 and wR=0.1755 for 3055 observed reflections with Ⅰ2σ(Ⅰ).X-ray diffraction study reveals that the title complex has an interesting 3D architecture via hydrogen bonding interactions and π-π interactions.The IR,TGA,XRD and luminescent properties of complex 1 were also studied. 相似文献

Metal-organic frameworks(MOFs), consisting of metal, anion and organic ligands, have attracted much attention. The structure of MOFs is affected by various factors. To explore the effects of metal ions, we synthesized six complexes, namely {[Me_2NH_2][Zn_4(H_2L)(L)]·2 H_2O·2 DMF}_n(1), {[Me_2NH_2]_2[Cd_2(L)]·2H_2O}_n(2), {[Me_2NH_2]_2[Ca_3(L)(μ-OH)_2(DMF)_2]·2H_2O}_n(3) and {[Me_2NH_2]_2[M_2(L)(μ-OH)]· H_2O·2DMF}_n(M = Co, 4; Ni, 5; Mn, 6), from a C_(2v)-based hexacarboxylate ligand([1,1';4',1']terphenyl-3,5,2',5',3',5'-hexacarboxylic acid(H_6L)) using metal-induced strategy. These MOFs were thoroughly characterized by single-crystal and X-ray diffraction, elemental analysis, Fourier-transform infrared spectra(FTIR) and photoluminescence. 相似文献

以采前套袋控制病原菌潜伏侵染的杨梅果实为材料,采后接种橘青霉病菌,旨在研究橘青霉侵染对杨梅果实酚类物质含量及相关氧化酶活性变化的影响。结果表明:橘青霉侵染初期,杨梅果实细胞多酚氧化酶(PPO)、过氧化物酶(POD)活性呈上升趋势,酚类物质快速合成以提高自身的抗病能力。而同时期苯丙氨酸解氨酶(PAL)活性并没有相应增加,反而下降较快,致使木质素合成受阻,说明橘青霉侵染虽然诱导杨梅果实产生一定的抗病性,但这种抗病能力有限。贮藏中后期,虽然POD活性略有下降,PPO活性保持平稳,但二者始终处于较高水平,从而导致前期积累的酚类物质被大量降解,加上前期木质素合成受阻的影响,橘青霉更容易穿透杨梅果实细胞壁,进入细胞组织内繁殖生长,最终导致果实腐败。 相似文献

介绍了用熔融-分相法制备掺杂不同浓度Fe3+离子的纳米TiO2材料,利用X射线衍射分析TiO2的析晶情况,关对制备出的TiO2材料的光催化性能进行初步测试.结果表明:随着Fe2O3浓度的增加,纳米TiO2降解甲基橙的效率先增加而后降低,当Fe与Ti的摩尔比为0.06时,掺杂Fe3+离子的TiO2降解甲基橙的能力最好. 相似文献
