Three-state photochromic switching in a silyl bridged diarylethene dimer
Jetsuda Areephong, Wesley R. Browne and Ben L. Feringa
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.
