Outline of Final Research Achievements

Recently, organic light-emitting transistors (OLETs) which combined organic light-emitting diodes (OLEDs) with organic thin film transistors (OTFTs) have being intensively investigated for application to display. They can control light emission by the gate voltage. So far, we have investigated light-emitting electrochemical cells (LECs) and electrochemical transistors (ECTs) independently. LECs have some advantages about a simple device structure and usage of air-stable metal cathode compared to OLEDs. ECTs also have unique features for lower driving gate voltage than that of OTFTs because the electrochemical doping becomes easier for the formation of the electric double layer in the ECTs. Therefore, a novel concept for the light-emitting electrochemical transistor (LECT) which consists of the light-emitting electrochemical cell (LEC) and the electrochemical transistor (ECT) was introduced.
