Electrochemistry and electrogenerated chemiluminescence of thiophene and fluorene oligomers. Benzoyl peroxide as a coreactant for oligomerization of thiophene dimers

Abstract: The electrochemical properties of oligomers of thiophene (with number of monomer units, n, from 2 to 12) and fluorene (n ¼ 3 to 7) were investigated. Both sets of oligomers were characterized by the presence of two oxidation and two reduction waves as determined by cyclic voltammetry (CV), with the reversibility of the waves depending on the structural properties of the compounds. The addition or removal of a third electron was found to be difficult relative to the second, a finding shown for conjugated oligom… Show more

“…Dye 1 showed very bright ECL and its efficiency is 4.5 times greater than that of reference compound [Ru(bpy) 3 ] 2+ . The value obtained is remarkably high as compared to those observed in other organic ECL dyes and fluorene compounds . From an energetic point of view, the reaction between the dication radical 1 2 + and TPrA .…”

“…This demonstrates a diffusion‐controlled process on the Pt surface in this potential window for all three well‐separated anodic steps. The next two reversible anodic one‐electron waves are consistent with oxidation of the central spirofluorene core . However, another hypothesis that cannot be excluded is that the reversible one‐electron oxidation waves are related to oxidation of the thiophene moieties.…”
