Abstract:
The synthesis and photochemical characterization of bicomponent molecular switches based on covalently tethered dithienylethene photochromes is described. Both photochromic units undergo complete switching between the fully cyclised and fully non-cyclised states despite a significant level of electronic communication between the individual units and their proximity.
