  Gold(I)-Coordination Triggered Multistep and Multiple Photochromic Reactions in Multi-Dithienylethene (DTE) Systems

  摘要：

  The preparation, characterization, and photochromic properties of a mononuclear gold(I) complex (100) with two identical DTE-acetylides and a dinuclear gold(I) complex (2000) with both DTE-acetylide and DTE-diphosphine are described. Both gold(I) complexes exhibit multistep and multiple photocyclization/cycloreversion reactions. Particularly, four-state and four-color photochromic switch is successfully achieved for the dinuclear gold(I) complex upon irradiation with appropriate wavelengths of light. In contrast, fully ring-closed form is unattained through multiple photocyclization for the two corresponding model organic compounds coupling with the same DTE units as gold(I) complexes but without gold(I)-participation. It is demonstrated that coordination of gold(I) ion to DTE-acetylides exerts indeed a crucial role in achieving stepwise and selective photocydization and cycloreversion reactions for both gold(I) complexes, in which the coordinated gold(I) atom acts as an effective "barrier" to prohibit intramolecular energy transfer between multi-DTE moieties.

  The reaction of 1,2-bis(5-(diphenylphosphino)-2-methylthien-3-yl) cyclopentene (PPh2-DTE-PPh2) with the triruthenium cluster precursor [Ru3O(OAc)6(py)2(CH3OH)](PF6) (1) gave monomeric or dimeric derivatives [Ru3O(OAc)6(py)2PPh2-DTE-PPh2}](PF6) ([2]PF6) and [Ru3O(OAc)6(py)2}2μ-PPh2-DTE-PPh2}](PF6)2 ([3]PF6). Reduction of [2]+ and [3]2+ afforded one- or two-electron-reduced neutral products Ru3O(OAc)6(py)2PPh2-DTE-PPh2} (2) and Ru3O(OAc)6(py)2}2μ-PPh2-DTE-PPh2} (3), respectively. These triruthenium complexes show remarkable photochromism through photochemical ring-closing (UV light irradiation) and ring-opening (Vis light irradiation) processes as well as electrochromic properties through oxidation/reduction in the triruthenium cluster. Both the photochromic and electrochromic properties of 2 and 3 are highly reversible.
