Doping of metal–organic frameworks towards resistive sensing

Abstract Coordination polymerization leads to various metal–organic frameworks (MOFs) with unique physical properties and chemical functionalities. One of the challenges towards their applications as porous materials is to make MOFs optimally conductive to be used as electronic components. Here, it...
