Electroluminescent materials methacrylate

Polyaniline Blends. Polyaniline doped with camphor sulfonic acid, PANI-CSA, in the form of a blend with poly(methyl methacrylate), PMMA, is also used as hole injection material in PPV-based LEDs owing to the low barrier for hole injection [209,210] and the match of the PPV electroluminescent emission with the transmittance window of the PANI-CSA/PMMA blend (Fig. 10). Blends of polyester resin (PES) with PANI-CSA were also used for this purpose [209]. The barrier height for hole injection at the PANI-CSA-PES/MEH-PPV blend was found to be dependent on the PANI-CSA concentration, ranging from about 0.02 eV at a concentration of 5% w/w to about 0.1 eV for pure PANI [209]. In the case of PANI-CSA-PMMA/PPV interfaces, the barrier height for hole...
