整洁的 pyridinium 的 radiolysis 行为离子的液体(IL ) 和他们的水的答案用毫微秒脉搏 radiolysis 技术被调查。离子的液体的 Radiolysis 例如 N-butylpyridinium tetrafluoroborate (BuPyBF4 ) ，导致了 solvated 电子和器官的激进分子的形成。Solvated 电子与 pyridinium 一半反应了生产一个 pyridinyl 激进分子，它能把电子转移到各种各样的领受人。在 BuPyBF4 并且在几混合物的导出溶剂的 butylpyridinyl 激进分子的电子转移率常数(例如， duroquinone ， 4,4-pyridine ， benzophenone ，并且 1,1-dimethyl-4,4-bypyridinium 二氯化物)(顺序的 k 108 L/(摩尔 s )比在水里并且在 i-PrOH 测量，但是比基于粘性估计的控制散开的率常数显著地高的那些低。在整洁的 BuPyBF4 的电子转移率常数比控制散开的值快一个数量级。这发现建议 Bu-PyBF4 溶剂充当不仅而且作为活跃溶质，例如在调停溶剂的反应。这些反应导致没有要求一个特定的激进分子的散开，经由干涉 pyridinium 组到达他们的最后的目的地的电子。

英文摘要：

The radiolysis behavior of neat pyridinium ionic liquids （ILs） and their aqueous solutions was investigated using nanosecond pulse radiolysis techniques. Radiolysis of the ionic liquids, such as N-butylpyridinium tetrafluoroborate （BuPyBF4）, resulted in the formation of solvated electrons and organic radicals. Solvated electrons reacted with the pyridinium moiety to produce a pyridinyl radical, which can transfer electrons to various acceptors. The electron-transfer rate constants of the solvent-derived butylpyridi- nyl radicals in BuPyBF4 and in several compounds （for example, duroquinone, 4,4＇-pyridine, benzophenone, and 1,1＇- dimethyl-4,4＇-bypyridinium dichloride） （k of the order 108 L/（mol s） were lower than those measured in water and in i-PrOH but were significantly higher than the diffusion-controlled rate constants estimated based on viscosity. The electron-transfer rate con- stants in neat BuPyBF4 were one order of magnitude faster than the diffusion-controlled values. This finding suggests that Bu- PyBF4 acts not only as solvent but also as active solute, such as in solvent-mediated reactions. These reactions result in electrons reaching their final destinations via intervening pyridinium groups without requiring the diffusion of a specific radical.
