Adjustment of the environmental acidity is a powerful method for fine-tuning the outcome of many chemical processes. Numerous strategies have been developed for the modification of pH in bulk as well as locally. Electrochemical and photochemical processes provide a powerful approach for on-demand generation of ion concentration gradients locally at solid-liquid interfaces. Spatially organized in individual way electrodes provide a particular pattern of proton distribution in solution. It opens perspectives to iontronics which is a bioinspired approach to signaling, information processing, and storing by spatial and temporal distribution of ions. We prove here that soft layers allow to control of ion mobility over the surface as well as processes of self-organization are closely related to change in entropy. In this work, we summarize the achievements and discuss perspectives of ion gradients in solution for information processing.
调节环境酸度是微调许多化学过程结果的有效方法。已经开发出许多用于整体以及局部调节pH值的策略。电化学和光化学过程为在固液界面局部按需产生离子浓度梯度提供了有力方法。以个体方式空间组织的电极在溶液中提供了特定的质子分布模式。这为离子电子学开辟了前景，离子电子学是一种受生物启发的通过离子的空间和时间分布进行信号传输、信息处理和存储的方法。我们在此证明，柔软层能够控制离子在表面的迁移率，并且自组织过程与熵的变化密切相关。在这项工作中，我们总结了溶液中离子梯度在信息处理方面的成果并讨论了其前景。
