Nanostructured Polymer Light-Emitting Diodes

Significance

There has been extensive research devoted to the improvement of polymer light-emitting diodes (PLED) by the addition of nanostructures to improve charge transport and overall efficiency within the device. Recently this has involved the use of inorganic nanoparticles; however, these often require non-trivial processing steps. Molecules similar to 1 have been shown to self-assemble into nanowires (J. Am. Chem. Soc. 2007, 129, 12386), and the authors demonstrate that uniformly distributed nanowires of 1 can be obtained within the device through in situ self-assembly. This facile, solution-processed, nanostructured PLED shows an increased performance by a factor of about two.
