“…The higher the concentration of the anionic surfactants, the more the micelle number increases. It might be more important that these anionic surfactants prevent a rapid degradation of the oxalates by the hydrolysis under alkaline conditions , because the negatively charged sulfate moiety of SDS would interrupt the contact between the active oxalates and the hydroxyl anions at the hydrophobic inside of the SDS micelle by the repulsive force of the negatively charged sulfate moieties at the periphery of the micelle. By contrast, the cationic surfactants take the hydroxyl ions in the micelle core to promote a significant degradation of the oxalates.…”

“…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.

The peroxyoxalate chemiluminescent reaction of bis(4 nitrophenyl) oxalate or bis(pentachlo rophenyl) oxalate with hydrogen peroxide in the presence of hematoporhyrin IX water insoluble derivative in micelles or associates of Pluronics F68, L64, L61 and the alternating copolymer dimethyl siloxane ethyl ene oxide is investigated. Pluronic L61, which forms large clusters in solution, has the greatest impact on the reaction quantum yield. The micelles influence on the efficiency of the reaction with bis(pentachlorophenyl) oxalate is stronger in comparison to that with bis(4 nitrophenyl) oxalate. The chemiluminescence quantum yield increases with the concentrations of fluorophore and hydrogen peroxide. If the polymer content is being varied, quantum yield passes through the maximum, which corresponds to the largest amount of particles containing both oxalate and porphyrin.

The chemiluminescence (CL) of bis(2,4,6-trichlorophyenyl) oxalate with hydrogen peroxide in the present of cationic surfactant and gold nanoparticles was studied. The CL emission was obviously enhanced in the presence of surfactant at a suitable concentration, with a synergetic catalysis effect exhibited. Different sizes of gold nanoparticles (15 and 50 nm) showed different effects on CL intensity. Mechanisms of the CL reaction and sensitization effect are discussed.
