| contents | A light-driven ultrafast sensor based on biocompatible solvatochromic metal-organic frameworks. Timofeeva, Maria Kenzhebayeva, Yuliya Burzak, Nikita Bazhenova, Agniia Lunev, Artem Novikov, Alexander S Bondarenko, Andrey B Shipilovskikh, Sergei A Dyachuk, Vyacheslav A Milichko, Valentin A 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 and 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. |
