• Coordination-driven nanosized lanthanide ‘Molecular Lanterns’ as luminescent chemosensors for the selective sensing of magnesium ions
  作者：Liang Zhao、Yang Liu、Cheng He、Jian Wang、Chunying Duan

  DOI：10.1039/c3dt51900g

  日期：——

  Novel cerium-based ‘Molecular Lanterns’ Ce-DBDS, Ce-DBBS and Ce-DBOS were achieved via self-assembly from bis-tridentate ligands H4DBDS, H4DBBS and H4DBOS, respectively. Structure analysis of Ce-DBDS shows that six oxygen atoms of the ether bond groups on the ligands form a lantern-like cavity inside the compound. Thus the ‘Molecular Lanterns’ exhibit crown ether recognition behavior and could be applied in luminescent magnesium chemosensors. The restricted geometry constraints of the internal cavities provide high selectivities of the lantern-like probes towards the Mg2+ ion over other different-sized metal ions such as Al3+, Li+, Ca2+, Na+, Ba2+ and K+. Ce-DBBS which contains three fully substituted benzyl groups exhibited better sensitivity by the cation–π interaction between Mg2+ and the benzyl group, compared to the Ce-DBDS. However, Ce-DBOS can work as an artificial chemosensor for selective fluorescent detection of Al3+ rather than Mg2+, due to its cavity being much smaller than Ce-DBDS and Ce-DBBS.

  新型铈基 "分子灯笼 "Ce-DBDS、Ce-DBBS和Ce-DBOS分别由双三叉配体H4DBDS、H4DBBS和H4DBOS自组装而成。Ce-DBDS的结构分析表明，配体上醚键基团的六个氧原子在化合物内部形成了一个灯笼状空腔。因此，"分子灯笼 "具有冠醚识别行为，可用于发光镁化学传感器。由于内部空腔的几何形状受到限制，灯笼样探针对 Mg2+ 离子具有很高的选择性，而对 Al3+、Li+、Ca2+、Na+、Ba2+ 和 K+ 等其他不同大小的金属离子则没有选择性。与 Ce-DBDS 相比，含有三个完全取代苄基的 Ce-DBBS 通过 Mg2+ 与苄基之间的阳离子âÏ 相互作用表现出更高的灵敏度。然而，由于 Ce-DBOS 的空腔比 Ce-DBDS 和 Ce-DBBS 小得多，因此它可以作为一种人工化学传感器，对 Al3+ 而不是 Mg2+ 进行选择性荧光检测。

• Oxidative coupling polymerization of bishydrazide for the synthesis of poly(diacylhydrazine): Oxidative preparation of oxidatively degradable polymer
  作者：Kentaro Nagashima、Nobuhiro Kihara、Yusuke Iino

  日期：2012.10.15

  The oxidative coupling polymerization of bishydrazide is successfully performed to form poly(diacylhydrazine) (PDAH), which is an oxidatively degradable polymer. Oxone is an effective oxidant, and a mixture of an aprotic polar solvent, water, and acetonitrile or N,N‐dimethylacetamide is necessary as the solvent. On treatment of PDAH with sodium hypochlorite solution or hydrogen peroxide, the PDAH is

  成功地进行了双酰肼的氧化偶联聚合反应，以形成聚（二酰肼）（PDAH），它是一种可氧化降解的聚合物。Oxone是一种有效的氧化剂，非质子极性溶剂，水和乙腈或N，N-二甲基乙酰胺的混合物是必需的溶剂。用次氯酸钠溶液或过氧化氢处理PDAH时，PDAH迅速氧化并降解为相应的二羧酸。当使用过氧化氢作为氧化剂时，为了有效降解，必须添加乙腈和碳酸钾。PDAH在空气中表现出高的热稳定性，并具有高的T g价值。在空气中未观察到氧化。因此，PDAH是一种可氧化降解的高性能聚合物，对氧气稳定。©2012 Wiley Periodicals，Inc.
