摘要
A hydrophobic thiol-functionalized ionic liquid (IL) was synthesized and immobilized tightly on a gold electrode surface via Au-S bond to construct a stable Au-IL vertical bar water interface. At the Au-IL vertical bar water interface, the electrochemiluminescence (ECL) of luminol-O-2 system was investigated. The ECL intensity of luminol-O-2 system at the Au-IL vertical bar water interface was much larger and more stable than that at Au vertical bar water interface. The enhanced ECL mechanism at the Au-IL vertical bar water interface was studied and discussed in details. (C) 2009 Elsevier B.V. All rights reserved.
