Electrochemical doping during light emission in polymer light-emitting electrochemical cells

Small-molecule light-emitting electrochemical cells: evidence for in situ electrochemical doping and functional operation.

We demonstrate that non-ionic small molecules (SMs) can function as the doping and emissive compound in light-emitting electrochemical cells (LECs), and that high brightness and decent efficiency can be attained for such devices. It is plausible that the expansion of the LEC library, to include easy-to-purify and tunable non-ionic SM compounds, could represent a viable path towards improved LEC...
