Surface-assisted cis-trans isomerization of an alkene molecule on Cu(110)

23 January, 2014 - 19:17

Chem. Commun., 2014, 50,1728-1730
DOI: 10.1039/C3CC48992B, CommunicationQiang Sun, Chi Zhang, Likun Wang, Zhiwen Li, Aiguo Hu, Qinggang Tan, Wei Xu
Interplay of STM imaging and DFT calculations demonstrates the isomerization of an alkene molecule on Cu(110) under ultrahigh vacuum conditions. We show that the on-surface cis-trans isomerization could efficiently occur well below room temperature, in which the surface is speculated to play a key role in assisting this isomerization process.
