“…Another simple method is the use of surfactants, which lead to changes in the microenvironments in which reactive intermediates take part in the chemiexcitation steps by interacting with the fluorophores. Several reports have dealt with the effects of surfactants on PO‐CL, and various effects of neutral, cationic and anionic surfactants on the CL efficiency have been documented , however, these results cannot be easily integrated into a simple system because surfactants behave in different ways depending on the reactants and the reaction conditions.…”

Abstract:The effect of several surfactants on peroxyoxalate chemiluminescence (PO-CL) using oligophenylenevinylene fluorophores was investigated. Among several oligophenylenevinylenes consisting of some stilbene units, linearly conjugated ones, such as distyrylbenzene and distyrylstilbene, effectively enhanced PO-CL efficiency. Various effects of anionic, cationic, amphoteric and non-ionic surfactants on the CL efficiency of PO-CL were determined using three oxalates and the distyrylbenzene fluorophore. Anionic and non-ionic surfactants effectively enhanced CL efficiency, in contrast to the negative effect of cationic and amphoteric surfactants.Non-ionic surfactants were also effective in CL reactions of oxalates bearing dodecyl ester groups by the hydrophobic interaction between their alkyl chains. Considering these results, the surfactants not only increase the concentrations of water-insoluble interacting species in the hydrophobic micelle cores, but also control rapid degradation of the oxalates by alkaline hydrolysis.
