摘要：

The light-emitting electrochemical cell (LEC) is used to measure the charge injection energy gap in semiconducting polymers. Simultaneous measurements of the onset of electrochemical doping, electrical injection, and electroluminescence from light-emitting electrochemical cells determine the magnitude of the exciton binding energy; the LEC data are consistent with the semiconductor model in which the exciton binding energy is small.
