Ionic liquids have continued to attract huge interest in modern science and technology in the last decade. The early stages of ionic liquids research have mainly focused on alternative green solvents for traditional volatile organic solvents due to the low volatility of ionic liquids. However, benefiting from their designable structure and properties, ionic liquids have been developed, in recent years, as a multifunctional platform to produce new advanced materials applicable to many technical fields. In this mini-review, recent progress in the newly developed ionic liquids and their interesting applications as functional components in perovskite solar cells, seawater desalination, tunable nanoreactors, and advanced intelligent materials such as wearable photo-electronic devices and soft robotics have been summarized, and the existing barriers and future trends have been critically analyzed and highlighted. We hope that it could be a useful guide for the design and understanding of ionic liquid-based advanced materials, and thus, motivating the future research and development of new functional ionic liquids in the broad fields of advanced materials.

在过去十年中，离子液体继续引起现代科学技术的巨大兴趣。由于离子液体的低挥发性，离子液体研究的早期阶段主要集中在传统挥发性有机溶剂的替代绿色溶剂。然而，受益于其可设计的结构和性能，离子液体近年来被开发为多功能平台，可用于生产适用于许多技术领域的新型先进材料。在这篇小型综述中，总结了新开发的离子液体及其在钙钛矿太阳能电池、海水淡化、可调纳米反应器以及可穿戴光电设备和软机器人等先进智能材料中作为功能组件的有趣应用的最新进展，并对现有障碍和未来趋势进行了批判性分析和强调。我们希望它能够为基于离子液体的先进材料的设计和理解提供有益的指导，从而推动未来在先进材料广泛领域中新型功能性离子液体的研究和开发。
