Facile and Fast Transformation of Nonluminescent to Highly Luminescent Metal–Organic Frameworks: Acetone Sensing for Diabetes Diagnosis and Lead Capture from Polluted Water

Metal–organic frameworks (MOFs) stand as one of the most promising materials for development advanced technologies owing to their unique combination properties. The conventional synthesis MOFs involves a direct reaction organic linkers and metal salts; however, postsynthetic modification is sophisticated route produce new or confer novel properties that cannot be attained through traditional methods. This work describes MOF-to-MOF transformation nonluminescent MOF (Zn-based Oxford University-1 material [Zn-BDC, where BDC = 1,4-benzene dicarboxylate] (OX-1)) into highly luminescent framework (Ag-based University-2 [Ag-BDC] (OX-2)) by simple immersion former in silver salt solution. conversion mechanism exploits uncoordinated oxygen atoms terephthalate found OX-1, instead unsaturated sites commonly employed, making much faster. derived from OX-1 OX-2 are exhibit selective response acetone, turning them candidate manufacturing fluorometric sensors diagnosis monitoring diabetes mellitus. Our methodology can extended other metals such lead (Pb). fabrication polymer mixed-matrix membrane containing used proof-of-concept capturing Pb ions (as pollutants) water. research instigates exploration alternative methodologies with special aptitudes photochemical sensing environmental applications water purification.
