We have liftoff! Tightly packed self-assembled monolayers (SAMs) of ultrarigid conjugated azobenzenes incorporated into a Hg-based junction undergo reversible photoisomerization (see picture). The current–voltage curves indicate that the junction operates as a current photoswitch as result of the forces expressed by the SAMs, which act as a light-powered cargo lifter.
