Modulating the rate of charge transport in a metal–organic framework thin film using host:guest chemistry

Abstract

Herein we demonstrate the use of host–guest chemistry to modulate rates of charge transport in metal–organic framework (MOF) films. The kinetics of site-to-site of charge hopping and, in turn, the overall redox conductivity, of a ferrocene-modified MOF can be altered by up to 30-fold by coupling electron exchange to the oxidation-state-dependent formation of inclusion complexes between cyclodextrin and channel-tethered metallocenes.
