研究開始時の研究の概要 |
Electrochemiluminescence (ECL) is light emission triggered electrochemically. Because only inorganic complexes can generate ECL in water, the proposed research plan aims to develop a bipolar electrochemical method for the ECL generation from organic molecules in aqueous solution. The method relies on the use of micelles generated by a redox-active surfactant where the organic molecule is entrapped and dissolved in water. Successively, an electrochemical stimulus causes the cleavage of the micelle and the release of the organic molecule onto the electrode surface, generating ECL emission.

研究実績の概要 |
The aim of the proposed research plan is to develop a bipolar electrochemical method for the generation of electrochemiluminescence (ECL) from organic molecules in aqueous solution. The method relies on the use of micelles generated by a redox-active surfactant where the organic molecule is entrapped and dissolved in water. At present, the micelle disruption method has been implemented to form a film of an organic molecule, such as 9,10-diphenylanthracene (DPA), on the electrode and, after addition of a coreactant like tri-n-propylamine (TPrA), ECL emission has been detected and the light intensity is correlated with the thickness of the film formed on the electrode.

1: 当初の計画以上に進展している
理由
The ECL system composed of DPA and TPrA has been deeply investigated and the experimental parameters to achieve ECL emission have been optimized.
The electrolytic micelle disruption method has been implemented and used to generate a film of DPA on the electrode.
ECL emission of the DPA molecule on the film state has been investigated.

今後の研究の推進方策 |
The electrolytic micelle disruption method will be developed with the aid of bipolar electrochemistry for the fabrication of gradient DPA films.
The detection of a gradient ECL emission from the DPA films will be investigated to find the suitable parameters for its recording.
