a, Scheme of the experimental setup. ZnTPP-COF monolayer membrane suspending on the SiNx/Si chip containing a 2 μm aperture is mounted on a Teflon disk, with both sides of the membrane in contact with aqueous solution. Ag/AgCl electrodes are applied to characterize the current-voltage response, where agarose salt bridges are used to eliminate the imbalanced redox potential at the electrode|electrolyte interface. b, Photograph of the disassembled electrochemical device. c, An empty SiNx aperture and a ZnTPP-COF monolayer membrane covered SiNx aperture.
