Photoswitchable Proton Conduction: Switching the Proton Conduction in Nanoporous, Crystalline Materials by Light (Adv. Mater. 8/2018)

Proton-conducting molecules in the pores of metal–organic frameworks change their conductivity upon photoswitching the host framework. In work by Lars Heinke and co-workers presented in article number 1706551, irradiation with light (green) causes trans–cis isomerization of the azobenzene components of the framework, switching the molecular interaction and the conductivity of the triazole guest molecules (center). The sample is mounted on interdigitated gold electrodes, which are used for measuring the conductivity.
