1.        H. B. Duan, X. M. Ren* et al.,‘Disorder-order transformation and significant dislocation motion cooperating with a surprisingly large hysteretic magnetic transition in a nickel-bisdithiolene spin system’, Inorg. Chem. 2013, 52, 3870-3877.

The compound [4'-CF(3)bzPy][Ni(mnt)(2)] (1) (where 4'-CF(3)bzPy = 1-(4'-(trifluoromethyl)benzyl)pyridinium and mnt(2-) = maleonitriledithiolate) was synthesized and displays a magnetic bistability with a surprisingly large thermal hysteresis loop (similar to 49 K). X-ray crystallographic studies reveal that in the high-temperature (HT) phase the anions and cations form mixed stacks, with alternating anion dimers (AA) and cation dimers (CC) in an ...AACCAACC... fashion along the crystallographic a + b direction, and disordered CF3 groups in the cations are aligned into a molecular layer parallel to the crystallographic (001) plane. However, in the low-temperature (LT) phase, the c-axis length of the unit cell is roughly doubled, and the asymmetric unit switches from one [4'-CF(3)bzPy][Ni(mnt)(2)] pair in the HT phase to two [4'-CF(3)bzPy][Ni(mnt)(2)] pairs. Most interestingly, the CF3 group in the cations becomes ordered, and the conformation of one of two crystallographically different cations changes significantly. A dislocation motion between the neighboring molecular layers emerges as well. The analyses of the magnetic susceptibilities and the density functional theory calculations suggest that the antiferromagnetic exchange interaction within one of two types of [Ni(mnt)(2)](2)(2-) (timers in the LT phase is much stronger than that within the [Ni(mnt)(2)](2)(2-) dimer in the HT phase. The lattice reorganization during this phase transition is proposed to be responsible for the wide thermal hysteresis loop.

简介

传统还原炔酰胺的方法主要集中于Lindlar催化剂或者Pd/C催化剂催化的氢气氢化还原,而朱红军教授课题组巧妙地利用炔烃的硼氢化反应实现了炔酰胺类化合物的还原,该反应是首例通过炔烃硼氢化加成反应还原炔烃的方法。为烯酰胺类化合物的合成提供了一个不可多得的方法。

该报道选用炔烃修饰1,8-萘酰亚胺荧光基团,设计了首例在水溶液中对叠氮酸进行检测的荧光探针。该探针既可以在Hela细胞中对叠氮酸进行监测,还可以在斑马鱼幼虫体内对叠氮酸进行成像。当生物体内叠氮酸含量超过阈值时,该探针所释放的荧光可以被设计成为一种预警机制。

该报道设计了合成了两例基于罗丹明B-芘双荧光基团化学传感器,对于Hg2+在色度、荧光信号上都表现出很高的选择性及很好的亲和性。由于结构的不同,硫化内酰胺环结构与Hg2+按照FRET机理进行作用,荧光呈现比率变化;而Hg2+则会使得单纯内酰胺环水解从而释放出罗丹明B及芘单体。因为Hg2+的嗜硫性,硫化内酰胺环结构具有更低的检出限及更少的检出时间。

Scheme:Schematic of the colorimetric detection strategy for Hg2+ and melamine based on cysteamine modified AuNPs

    该报道是利用半胱氨酸修饰的金纳米颗粒(CA-Au NPs)来定量比色检测Hg2+和三聚氰胺。通过调节pH,半胱氨酸末端的氨基基团质子化,来调控半胱氨酸修饰的纳米金表面电荷。在酸性pH,由于氨基基团,CA-AuNPs表面带有正电荷可能吸附三聚氰胺导致CA-AuNPs聚集;在碱性pH,氨基基团去质子化,如果Hg2+存在时,会形成N-Hg2+-N结构导致CA-AuNPs聚集。该方法对于Hg2+和三聚氰胺的检出限分别为30nM80nM,与其他的单分析物方法相比,检出限更低。该传感器的检测机理对于三聚氰胺来说是基于静电吸引,对于Hg2+来说是基于N-Hg2+-N结构,这些可通过Zeta电位来验证。对于金纳米颗粒,这种新颖的一步表面修饰方法适合有效地分析大量的样品,这也为小型化的Hg2+和三聚氰胺的发展开创了心得机遇。

简介

二唑由于其独特的NO原子使得其表现出高的生物活性,且在农药和医药方面有着广泛的应用。本课题组利用生物电子等排原理将脂肪酰胺潜伏于二唑中。这样不仅保留了酰胺结构,还引入了二唑这样一个高活性基团。鉴于此,本文设计合成了系类含1,2,4-二唑和1,3,4-二唑的邻氨基苯甲酰胺类化合物。生物活性测试结果表现,化合物60.4 mg L?1对小菜蛾的杀虫活性以及在1 mg L?1对甜菜夜蛾的杀虫活性与氯虫苯甲酰胺相接近。
