装饰有能够主动中和生物病原体的光敏自清洁材料的可穿戴个人防护设备需求很高。在这里，我们开发了一系列能够应对这一挑战的可溶液加工的结晶多孔材料。涂有这些材料的纺织品具有广泛的功能，包括吸收日光时自发产生活性氧（ROS），以及在黑暗条件下长期储存ROS。这些材料的ROS产生和储存能力可以通过前体的化学工程进一步提高，而不会改变三维组装的超结构。与传统的TiO 2或C3 N4自清洁材料相比，氟化分子涂层材料霍夫-101-F显示出10 - 60倍的ROS生成能力和10 - 20倍的ROS储存能力。我们的研究结果为进一步开发自清洁纺织品涂层铺平了道路，以便在日光和无光条件下快速灭活高传染性病原菌。
Wearable personal protective equipment that is decorated with photoactive self‐cleaning materials capable of actively neutralizing biological pathogens is in high demand. Here, we developed a series of solution‐processable, crystalline porous materials capable of addressing this challenge. Textiles coated with these materials exhibit a broad range of functionalities, including spontaneous reactive oxygen species (ROS) generation upon absorption of daylight, and long‐term ROS storage in dark conditions. The ROS generation and storage abilities of these materials can be further improved through chemical engineering of the precursors without altering the three‐dimensional assembled superstructures. In comparison with traditional TiO2or C3N4self‐cleaning materials, the fluorinated molecular coating material HOF‐101‐F shows a 10‐ to 60‐fold enhancement of ROS generation and 10‐ to 20‐fold greater ROS storage ability. Our results pave the way for further developing self‐cleaning textile coatings for the rapid deactivation of highly infectious pathogenic bacteria under both daylight and light‐free conditions.
