Abstract

Flip-flop: Mechanical and opto-mechanical switching cycle of a nanoswitch made up of single dithioazobenzene chromophore suspended between two gold tips (see picture). Mechanical switching proceeds on the ground-state S0 surface while successful optical switching via S1 state requires mechanical assistance.
