Redox-Active Metal-Organic Framework Nanocrystals for the Simultaneous Adsorption, Detection, and Detoxification of Heavy Metal Cations.

ABSTRACT: The widespread contamination of water by heavy metals requires materials capable of efficient capture, in situ detoxification, and real-time monitoring. This work examines a series of redox-active metal-organic frameworks (MOFs) constructed from hexahydroxytriphenylene (HHTP) ligands coordinated to cobalt, nickel, and copper (Co-HHTP, Ni-HHTP, and Cu-HHTP), revealing how framework architecture and metal coordination environment dictate adsorption capacity, redox activity, and detection performance toward cadmium (Cd²⁺), mercury (Hg²⁺), and lead (Pb²⁺) ions. Among the series, Co-HHTP exhibits the highest uptake capacities of 169, 733, and 554 mg g^-1 for Cd²⁺, Hg²⁺, and Pb²⁺, respectively, attributed to its trigonal
