Outline of Final Research Achievements

We proposed a new type of single-molecular light-emitting device fabricated in a nanogap electrode, where the light emission is obtained through an energy transfer from host to guest molecules. The efficient ambipolar charge injection from similar electrodes (gold) was realized by using a blend film of a light-emitting semiconducting polymer and ionic liquid, that is, a light-emitting electrochemical cell (LEC). In addition, due to the appropriate surface treatment for the SiO2 substrate, the active layer was successfully formed only on the electrodes and nanogap. Therefore the light emission is expected to occur at the nanogap. Finally, a current driven light emission from the nanogap LEC was successfully obtained.
