Abstract
Third-harmonic generation (THG) near-field scanning optical microscopy (NSOM) was used to investigate both as-cast and thermally annealed films of poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV). Many small domains with increased ground-state π-electron delocalization were observed in the thermally annealed films. The results indicate that the ground-state electronic properties of conjugated polymer films become highly inhomogeneous upon annealing.
