Conjugated polymer/molten salt blend optimization.
Light-emitting electrochemical cells with low current threshold can be realized through mixing conjugated polymers and molten salts. Current drive capability is proportional to the overall interface perimeter of the planar, discotic molten salt domains inserted into the polymer matrix. Electric force microscopy indicates that this interface perimeter exhibits a specific dependence on the molten salt content in the active layer, with a well-defined maximum. We show that this maximum corresponds to an optimal current drive.
