Abstract

We have found by NEXAFS spectroscopic studies that a PPV derivative (CzEh-PPV) bearing the carbazole pendants form new intragap states when contacted with calcium metal. Moreover, the polymer exhibited much more balanced mobilities of holes and electrons than PPV and MEH-PPV. Such characteristics are believed to bring about low turn-on electric field and improved efficiency for the LED device fabricated with the polymer.
