Abstract
Coordination polymerization produces a variety of metal-organic frameworks (MOFs), each with its own set of physical & chemical properties. Making MOFs suitably conductive in nature, is one of the hurdles faced to be utilized its potential practical applications. To explore the electrical conductivity’s features of MOFs, NH2-Al-MOF, ZnQ@ZIF-8 and Al-MIL-53 MOF have been treated with NaOH, H2SO4, and HCl. Acid/Alkaline doped MOFs have been utilized to prepare conducting thin films on indium tin oxide (ITO) slides using drop-casted method. Electrical feature analysis has indicated reduction in overall resistance of NH2-Al-MOF < ZnQ@ZIF-8 < Al-MIL-53. The prepared MOFs thin films have been used for malathion detection. We have found limit of detection (LOD) i.e., 1.668 mg/L 2.386 mg/L and 2.397 mg/L for malathion using doped MOFs, respectively.
