Abstract

We use ultrahigh-vacuum conducting atomic force microscopy to probe the local current distributions in spin-cast thin films from the solutions of poly (2-methoxy-5-(2′- ethylhexyloxy)-1, 4-phenylenevinylene)(MEH-PPV) and poly (9, 9-di-n-octyl-2, 7- fluorene)(PFO). We found that spatially homogeneous distribution of the ordered structures (well-packed chains and/or aggregates) in MEH-PPV can be controlled by the selection of ...
