초록

NEXAFS spectroscopy of conjugated polyelectrolytes used as the electron transport layer in polymer light-emitting diodes reveals a substrate-dependent accumulation of charged groups at the surface (see figure). The measurements are also consistent with a preferential orientation of tetrahedral counterions at the surface.
