Abstract
We reported electrochemiluminescence (ECL) in which light is emitted from the excited state of a redox-active material generated by electrochemical reactions. We applied AC driven system to enable quick emission response and high emission intensity. In this paper, we report that electrochemically triggered upconverted emission through triplet–triplet energy transfer (TTET) and subsequent triplet–triplet annihilation upconversion (TTA-UC) is observed for the first time in the electrochemiluminescence properties of a Ru complex/diphenylantracene (DPA) containing electrochemical cell.
