General description

12-冠醚-4是一种冠醚，通常用作配位化学中的配体。由于对锂阳离子具有很强的特异性螯合能力，它还是一种锂离子载体。

Application

12-冠醚-4可用作：
  • 通过阴离子开环聚合反应以六乙基环三硅氧烷单体和NaOH催化剂合成聚（二乙基硅氧烷） (PDES)
  • 作为添加剂用于通过芳基溴与二芳基甲烷之间的钯催化交叉偶联反应制备三芳基甲烷衍生物
  • 有机合成中的相转移催化剂

In this study honeycomb-like NiO nanostructures were grown on nickel foam by a simple hydrothermal growth method. The NiO nanostructures were characterized by field emission electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) techniques. The

Antimicrobial agents containing symmetrical triiodides complexes with halogen bonding may release free iodine molecules in a controlled manner. This happens due to interactions with the plasma membrane of microorganisms which lead to changes in the structure of the triiodide anion.
