| Outline of Research at the Start |
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.

| Outline of Final Research Achievements |
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. 9,10-diphenylanthracene (DPA) was emplyed as a model organic compound to establish the electrochemical methodology. DPA was incorporated in micelles generated from a redox-active surfactant and then solubilized in water where, after surfactant oxidation, could be released in the proximity of the electrode surface due to the cleavage of the surfactant micelles. Scanning at positive potentials and in presence of a suitable coreactant, such as oxalic acid, DPA oxidation leaded to the generation of a light emission, namely ECL, in water.

| Academic Significance and Societal Importance of the Research Achievements |
The proposed research aims to develop a method for the generation of electrochemiluminescence, that is a light emission induced electrochemically, from organic molecules in water, avoiding the use of organic solvents that are toxic and harmful for the environment.
