We find that DES molecules on the silver surface adsorb intact and adopt a trans-conformation. On the more reactive copper surface, O-H bond cleavage results in molecular adsorption in the cis-conformation, thus providing the means of obtaining different adsorption geometries. The difference in isomerism is reflected in the observed self-assemblies which exhibit room-temperature stability.eninfo:eu-repo/semantics/closedAccessCis-Trans IsomerizationBisphenol-AMoleculePhotoisomerizationTrimersNetworkStmArticle10.1039/c8cc06632a2-s2.0-85055768532
