  Phosphonium ionic liquids: design, synthesis and evaluation of biodegradability

  摘要：

  采用二氧化碳顶空试验（ISO 14593）评估了一系列膦离子液体（ILs）的生物降解性。目标是其中一个烷基取代基含有酯、醚、醇或烯官能团以促进生物降解的四烷基鏻阳离子。这些阳离子与卤化物、三酰亚胺和辛基硫酸根阴离子配对。与之前研究的含有酯基和辛基硫酸根阴离子的二烷基咪唑鎓和烷基磷鎓惰性离子相比，鏻惰性离子的生物降解性相对较低。

  Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution. This study shows that IL-generated porous morphology alone is not enough to provide effective extraction media: careful choice of the organic polymer and the precursor with close sol-gel reactivity must be made to ensure effective chemical bonding of the organic polymer to the created sol-gel material to be able to provide the desired sorbent characteristics.
