金属卤化物MCl2(M=Pb2+,Cd2+,Co2+)分别与苯并噻唑(btz)在浓盐酸中、80 ℃下反应,合成了3种有机-无机杂化化合物:(btzH)[(PbCl3)] (1),(btzH)2[CdCl4]·2H2O (2)和(btzH)2[CoCl4]·2H2O (3),其中化合物2和3结构相似。对化合物1~3进行了粉末衍射、红外和紫外光谱、元素分析、热重分析以及X射线单晶衍射表征。荧光测试发现:化合物1~3在393 nm处有发射峰,该荧光来源于苯并噻唑环中电子的π…π跃迁。 相似文献

在三氟化硼乙醚(BFEE)-聚乙二醇(分子量400,PEG400)混合电解质溶液中,1,8-亚乙基萘直接阳极氧化聚合可以获得自支撑聚(1,8-亚乙基萘)膜.单体在三氟化硼乙醚+10%PEG400中的起始氧化电位为0.95 Vversus SCE,远低于单体在0.1 mol.L-1四氟化硼四丁基胺-乙腈溶液中的起始氧化电位(1.38 VversusSCE).同时PEG400的加入可以有效改善单体在三氟化硼乙醚中的溶解性.UV-Vis,FTIR和1H-NMR确定了1,8-亚乙基萘在4,5位聚合,荧光光谱表明固态及可溶聚(1,8-亚乙基萘)膜是蓝色发光材料. 相似文献

在浓盐酸水溶液中,碘化N,N-二甲基-1,5-二氮杂环[3.2.1]辛烷([3.2.1-Me2dabco]I2)和碘化1-氨基-1,4-二氮杂环[2.2.2]辛烷([2.2.2-NH2dabco]I)与氯化铜反应得到2种有机-无机杂化铜化合物[3.2.1-Me2dabco][CuCl4](1)和[2.2.2-NH2dabco][CuCl4](2)。X射线单晶结构衍射证实化合物1和2中的无机阴离子是[CuCl4]2-四面体。化合物1和2表现出可逆的热致变色现象,随着温度升高,它们的颜色从黄色变为红色,这应该是由[CuCl4]2-四面体的变形引起的。 相似文献

新颖四核W-Cu-S簇合物[(η5-C5Me5)WS3Cu3Br(Py)3(dppm)](PF6)的合成和晶体结构 总被引:1,自引:0,他引:1
In the presence of NH4PF6, reaction of [PPh4][(η5-C5Me5)WS3Cu3Br(dppm)] with excess pyridine afforded red prismatic crystals, [(η5-C5Me5)WS3Cu3Br(Py)3(dppm)](PF6) (1). It was characterized by elemental analy-sis, IR, UV-vis and 1H NMR spectroscopy and X-ray diffraction. 1 crystallizes in an orthorhombic system with space group Pna21 and unit cell parameters a=2.1124(4)nm, b=1.8944(4)nm, c=1.3338(2)nm, V=5.3375(19)nm3, Z=4, Dc=1.807g·cm-3,Mr=1452.42, F(000)=2864, μ=4.342mm-1, R1=0.0487, wR2=0.1027. The structure of the cluster cation contains an incomplete cubane-like WS3Cu3 core where Cu(1) and Cu(2) atoms are bridged by a dppm ligand. Each of the three Cu atoms adopts a distorted tetrahedral coordi-nation geometry. The W-Cu(1), W-Cu(2) and W-Cu(3) distances are 0.27698(17)nm, 0.2772(17)nm, and 0.27065(9)nm, respectively.

A novel 1,2,3-triazolyl-containing ligand(H2L) with long donor arms extending from the central pyridyl linker was synthesized by click cycloaddition of 2,6-bis(azidomethyl)pyridine and 2-((prop-2-yn-1-yl(pyridin-2-ylmethyl)amino)methyl)phenol. Further treatment of the ligand H2 L with zinc(Ⅱ) perchlorate in the presence of triethylamine, followed by anion exchange with Na[BPh4], provided a dinuclear zinc(Ⅱ) complex [Zn2L][BPh4]2·2DMF(1). Complex 1 crystallizes in monoclinic, space group P21 with a = 10.4873(4), b = 14.9078(5), c = 25.8620(9) A, β = 94.566(2)o, V = 4030.5(2) A3, Z = 2, μ = 0.657 mm-1, Dc = 1.324 Mg/m3, T = 296(2) K, C93H91N13B2O4Zn2, Mr = 1607.19, F(000) = 1684, S = 0.958, R = 0.0271 and wR = 0.0607. In the structure of cation, the phenolate oxygen atoms of ligand act as the bridging nodes to form a rhombic Zn2(OAr)2 core. 相似文献
