Abstract

The design of fast, endurant, and biocompatible porous frameworks with solvatochromism, aimed to addressing the multiple visual sensing of chemicals, still remains a challenge. Here, we report on a solvatochromic metal-organic framework (MOF) based on cobalt and trimesic acid. We examined its solvatochromism through the solvent exchange and revealed high selectivity to water/dimethylformamide combination. The color change over 50 cycles during the solvent exchange occurs for 0.1 s, being 2 orders of magnitude faster than for existing MOFs. Despite the cobalt content, toxicity assays in vivo and in vitro revealed high biocompatibility of the MOF. The latter allowed implementing the fastest, highly-endurant and biocompatible MOF-based visual sensor of humidity in a desiccator for storage of water-sensitive goods and chemicals. Finally, for such a sensor, we demonstrated its multiple uses through remote light-driven recovery that contributes to the sustainability of this functional MOF.

基于生物相容性溶变色金属有机框架的光驱动超快传感器。

设计具有溶解变色功能的快速、持久和生物相容性多孔框架，以解决化学品的多重视觉传感问题，仍然是一项挑战。在此，我们报告了一种基于钴和三甲基酸的溶解变色金属有机框架（MOF）。我们通过溶剂交换研究了它的溶变色性，发现它对水/二甲基甲酰胺组合具有高选择性。在溶剂交换过程中，50 个循环的颜色变化时间为 0.1 秒，比现有 MOF 快 2 个数量级。尽管含有钴，但体内和体外毒性试验显示，这种 MOF 具有很高的生物相容性。这使得我们能够在用于储存对水敏感的物品和化学品的干燥器中，实现基于 MOF 的最快、高耐久性和生物相容性的湿度视觉传感器。最后，我们展示了这种传感器的多种用途，包括通过远程光驱动恢复，这有助于这种功能性 MOF 的可持续发展。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
