Using small-angle neutron scattering to investigate the aggregation of self-assembling molecules is well established. Some of these molecules are electrochemically useful, for example, in electrochromic devices. Electrochemistry can also be used in some cases to induce aggregation. Here, we describe an approach whereby electrochemistry can be directly carried out on a sample in the neutron beam, allowing us to monitor changes directly in situ. We exemplify with two examples but highlight that there are many other potential opportunities.
使用小角中子散射来研究自组装分子的聚集已得到充分确立。其中一些分子在电化学方面具有用途，例如在电致变色器件中。在某些情况下，电化学也可用于诱导聚集。在此，我们描述了一种方法，通过该方法可以在中子束中的样品上直接进行电化学操作，从而使我们能够直接在原位监测变化。我们举了两个例子进行说明，但要强调还有许多其他潜在的机会。
