A dual-emissive metal–organic framework was synthesized, and it represents the first MOF-based fluorescent ratiometric sensor for the turn-on sensing of hypochlorite with high efficiency and specificity.
Lewis basic site-functionalized porous Cd(ii)-MOF as a bi-functional fluorescent sensor of glyphosate and Cr3+ with exceptional LODs.
A new three-dimensional (3D) metal–organic framework exhibits high sensitivity and selectivity for Al3+ ions as a “turn on” fluorescent sensor.
