Abstract

Pyridine-derivatized dithienylethene dyes form complexes with W(CO)₅, Re(CO)₃(bpy)⁺, or Ru(NH₃)₅ ²⁺. The photochromism is retained for W and Re complexes: the highly colored closed forms can be produced from the respective open ones by UV irradiation, while the open forms are regenerated by red-light irradiation. Moreover, the complexes with W and Re are fluorescent, the emission intensity being strongly dependent on the state of the dithienylethene ligand. Ru forms complexes with both open and closed forms of .dithienylethenes. However, these species cannot be converted to each other photochemically since colored closed dithienylethene ligands are stabilized by coordination to Ru. The dithienylethene-metal complexes are potential light switches.
