The access to electroactive metal-organic frameworks (MOFs) and the ability to manipulate their electrical conductivity with external stimuli are vital for the realization of MOF-based sensors and electronic devices. A blue-colored electroactive MOF (BMOF) was constructed using 1,2,4,5-tetrakis-(4-carboxyphenyl) benzene (TCPB) struts and redox-active N,N'bis(4-pyridyl)-2,6-dipyrrolidylnaphthalenediimide (BPDPNDI) pillars. Uniform BMOF films grow selectively on ZnO-coated substrates. Electrical conductivity of BMOF film is ca. 6x10-5S/m (25 °C), which surges up to 2.3 x 10-3 S/m upon infiltration of π_acidic methyl viologen (MV2+) guests, but remains unchanged after being exposed to a C60 solution, as the latter gets size-excluded. These results demonstrate for the first time that the conductivity of MOFs can be fine-tuned by doping them with guest π-systems that can promote electron delocalization by forming π-donor/acceptor (D/A) stacks with the redox-active ligands.
