2022 Fiscal Year Research-status Report

Electrochemiluminescence of organic molecules in water using the bipolar electrolytic micelle disruption method

Research Project

Project/Area Number 22K14708
Research InstitutionTokyo Institute of Technology

Principal Investigator

ビラニ エレナ  東京工業大学, 物質理工学院, 特任助教 (40943618)

Project Period (FY) 2022-04-01 – 2024-03-31
KeywordsElectrochemiluminescence / Bipolar Electrochemistry / Organic Molecules / Micelles / Electric Fields
Outline of Annual 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. 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.

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

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.

Strategy for Future Research Activity

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.
