The water-stable, porphyrin-based metal-organic framework (MOF) demonstrates a unique color change in response to acids' pK(a) and concentrations, attributed to the protonation of N-atoms within the porphyrin ligand. This MOF has potential for detecting acidic pesticides in water samples, providing a simple and rapid method for identifying different levels of acidity.
A water-stable, porphyrin-based metal-organic framework (MOF) produces a distinct colour change in response to acids' pK(a) and concentrations. This colour change is associated with the protonation of the N-atoms within the porphyrin ligand present in the MOF structure. As a proof-of-concept, we demonstrate the use of this MOF for detecting traces of different acidic pesticides present in water samples spontaneously.
