摘要：
A fluorescent sensor Hn based on β-diketone derivative for Th<sup>4+</sup>ions was designed and investigated, which showed high selectivity in the present of other metal ions even UO<inf>2</inf><sup>2+</sup>in CH<inf>3</inf>OH:H<inf>2</inf>O (v/v = 2:8, pH = 7.2) solution. Meanwhile, the binding mode of the sensor Hn with Th<sup>4+</sup>ions was found to be 1:1 with association constant of 2.46 × 10<sup>4</sup> M<sup>−1</sup><inf>.</inf>And there was linear relationship between the fluorescent intensity of Hn-Th<sup>4+</sup>and the concentration of Th<sup>4+</sup>ions covering a range of 0.06 μM–1.0 μM and the detection limit was 0.0344 μM. At the same time, the interaction properties between the sensor Hn and Th<sup>4+</sup>ions and the fluorescent mechanism were investigated by IR,<sup>1</sup>HNMR and DFT. Most importantly, this fluorescent sensor was successfully utilized for the fluorescent imaging of Th<sup>4+</sup>ions in living cells. ©2017 Elsevier B.V.

摘要：
Understanding the photochromic mechanism of MOCs, regulating and controlling their structure and related photochromic properties is one of the focuses of chemistry and materials science. In this paper, two isoreticular metal-organic complexes have been synthesized by reaction of Zinc nitrite and H(6)ttha in the presence of bpee or bpea as co-ligand, respectively. The photochromic properties of complex 1 and 2 have been investigated. Even though both complexes holding similar framework, it is intriguing that complex 1 with conjugated co-ligand bpee displays remarkable photochromism property, but this photochromic phenomenon almost disappears in complex 2 when the conjugated co-ligand bpee is replaced by the non-conjugated coligand bpea. The possible photochromic mechanism is illustrated in detail. What's more, the relationship of structure-property has been discussed. (C) 2017 Elsevier B.V. All rights reserved.

摘要：
Three two-dimensional metal-carboxylate frameworks (MCFs), namely Zn<inf>3</inf>(BDC)<inf>3</inf>(py)<inf>2</inf>·2DMF (1), Mn<inf>3</inf>(BDC)<inf>3</inf>(DMF)<inf>4</inf>(2) and Co<inf>3</inf>(BDC)<inf>3</inf>(DMF)<inf>2</inf>(py)<inf>2</inf>(3) [H<inf>2</inf>BDC = 1,4-benzene dicarboxylic acid, py = pyridine, DMF = N,N′-dimethylformamide], have been synthesized by reaction of the M(NO<inf>3</inf>)<inf>2</inf>and H<inf>2</inf>BDC with py as base and DMF as solvent, under the microwave-assisted solvo-thermal conditions. Three MCFs were characterized by single crystal X-ray diffraction and mensurated its fluorescent or magnetic behaviors. The structural analyses reveal that 1-3 are constructed of the slightly dissimilar carboxylate bridged linear M<inf>3</inf>(RCOO)<inf>6</inf>(L<inf>T</inf>)<inf>2/4</inf>clusters where the coordination terminal ligand (L<inf>T</inf>) are py in 1, DMF in 2 and py/DMF in 3, respectively. The results demonstrated the different metal ions in two side of every SBU inclined to coordinate their respectively selected L<inf>T</inf>. The time-dependent density functional theory (TDDFT) calculations of 1 show that the emission peak of 423-428 nm (the experimental value is 425 nm) might be derived from the energy transition on the ligand-to-ligand charge transfer (LLCT) where electron densities residing on the π-bonding orbital of BDC<sup>2-</sup>are transferred to the π∗-anti-bonding orbital of pyridine. Variable-temperature magnetic susceptibility studies indicate the presence of antiferromagnetic exchange coupling within the M<inf>3</inf>-units of 2 and 3. ©The Royal Society of Chemistry 2016.

摘要：
A novel rhodamine-based dual probe Rh-2 for trivalent ferric ions (Fe3+) was successfully designed and synthesized, which exhibited a highly sensitive and selective recognition towards Fe3+ with an enhanced fluorescence emission in methanol-water media (v/v = 7/3, pH = 72). The probe Rh-2 could be applied to the determination of Fe3+ with a linear range covering from 3.0 x 10(-7) to 1.4 x 10(-5) M and a detection limit of 1.24 x 10(-8) M. Meanwhile, the binding ratio of Rh-2 and Fe3+ was found to be 1:1. Most importantly, the fluorescence and color signal changes of the Rh-2 solution were specific to Fe3+ over other commonly coexistent metal ions. Moreover, the probe Rh-2 has been used to image Fe3+ in living cells with satisfying results. (C) 2016 Elsevier B.V. All rights reserved.

摘要：
A new Schiff base fluorescence probe, 3-Allylsalicylaldehyde salicyl-hydrazone (L), for Mg2+ was designed and synthesized. The fluorescence of the sensor L was enhanced remarkably by Mg2+ with 2: 1 binding ratio, and the binding constant was determined to be 1.02 x 10(7) M-1. Probe L had high sensitivity for Mg2+ in a solution of DMF/water (4: 1, v/v, pH 7.5), and the detection limit was 4.88 x 10(-8) mol/L. Common coexistent metal ions, such as K+, Na+, Ag+, Ca2+, Zn2+, Ba2+, Bi2+, Cu2+, Ni2+, Hg2+, Fe3+, and Al3+, showed little or no interference on the detection of Mg2+ in solution. The fluorescence probe L, which was successfully used for the determination of trace Mg(II) in real samples, was shown to be promising for liquid-phase extraction coupled with fluorescence spectra.

摘要：
With the fast development of nanoscience and nanotechnology, the nanomaterials have attracted multidisciplinary interests. The high specific surface area and large numbers of oxygen-containing functional groups of graphene oxides (GOs) make them suitable in the preconcentration and solidification of radionuclides from wastewater. In this paper, mainly based on the recent work carried out in our laboratory, the efficient elimination of radionuclides using GOs and GO-based nanomaterials as adsorbents are summarized and the interaction mechanisms are discussed from the results of batch techniques, surface complexation modeling, spectroscopic analysis and theoretical calculations. This review is helpful for the understanding of the interactions of radionuclides with GOs and GO-based nanomaterials, which is also crucial for the application of GOs and GO-based nanomaterials in environmental radionuclide pollution management and also helpful in nuclear waste management.

摘要：
A novel β-cyclodextrin modified, multifunctional, layer-by-layer graphitic carbon nitride (g-C3N4/β-CD) was successfully synthesized and applied as an effective adsorbent for the removal of methyl orange (MO) and Pb(ii) from aqueous solutions under various environmental conditions (e.g., solution pH, solid content, contact time and temperature). The kinetic results indicated that the adsorption was dominated by chemisorption, and the higher adsorption capacity of g-C3N4/β-CD was attributed to it having more oxygen-containing functional groups than g-C3N4. The Langmuir, Freundlich and Sips models were applied to simulate the adsorption isotherms of MO and Pb(ii), and the results demonstrated that the adsorption of MO was attributed to multilayer adsorption, while the coverage adsorption of Pb(ii) on the g-C3N4/β-CD was monolayer adsorption. The thermodynamic parameters showed that the adsorption of both MO and Pb(ii) was spontaneous and endothermic. The DFT calculations further evidenced the surface complexation and electrostatic interaction of Pb(ii) on the g-C3N4 and g-C3N4/β-CD, whereas, the interaction of MO with g-C3N4 and g-C3N4/β-CD was mainly attributed to hydrogen bonds and strong π-π interactions. The results demonstrated that g-C3N4/β-CD is a promising material for the efficient removal of organic and inorganic pollutants in environmental pollution remediation. © 2016 The Royal Society of Chemistry.

摘要：
Understanding the rate and extent of 63Ni(II) sorption and desorption on/from mineral surfaces are important to predict its mobility performance in the natural environment. We herein systematically investigated the effects of pH, electrolyte cations, humic acid (HA) and temperature on 63Ni(II) sorption/desorption on/from Na-montmorillonite. The results indicated that the sorption/desorption of 63Ni(II) on/from Na-montmorillonite were strongly dependent on pH and electrolyte cations. Desorption abilities of 63Ni(II) were Na+ ≈ K+ > Ca2+ ≈ Mg2+ at the cationic concentration of 0.2 mol/L, which was associated with the clay tactoid size. The kinetic results suggested that 63Ni(II) sorption/desorption initially increased rapidly and remained constant as time increasing. The presence of HA influenced 63Ni(II) sorption clearly and promoted 63Ni(II) desorption as a result of the dissolution of ternary surface complexes. Increasing temperature was favorable for the sorption reaction owing to the formation of strong inner-sphere complexes, however, hampered the desorption reaction because of the increased stability of inner-sphere complexes or the aggregation of montmorillonite. The results are crucial to understand the physicochemical behavior of radionickel in the natural environment. © 2016 Elsevier B.V.

摘要：
设计合成了一种新的二（2-（乙硫基）乙基）胺功能化的苯并噻唑希夫碱衍生物（TBT），采用红外光谱、核磁共振光谱、元素分析进行其结构表征。研究了其光谱特性，并考察了该衍生物对金属离子的传感性能。研究结果表明TBT在四氢呋喃水溶液（v：v=1：1）中，对Hg^2＋显示荧光开关的特性，并且在Ag^2＋和Co^2＋等其它离子的存在下具有较高的选择性和灵敏性，它们之间的结合比例为1：1。
