Cover Picture: Recent advances on MOF‐based colorimetric sensors (BKCS 10/2025) Solmin Lee, Hyejin Yoo, Jin Yeong Kim

The cover image illustrates a security checkpoint symbolizing metal‐organic framework(MOF)‐based colorimetric sensors. Various MOF sensors with carefully engineered properties selectively response to their targeted analytes, by means of color changes. The colorimetric responses of the sensors enable facile and intuitive detection of selected chemical species. Details on the role of MOFs in the sensing mechanisms are available in the review article by Solmin Lee, Hyejin Yoo, and Jin Yeong Kim . image
