Unusual nondispersive ambipolar carrier transport and high electron mobility in amorphous ter(9,9-diarylfluorene)s.
Nondispersive ambipolar carrier transport with comparably high electron and hole mobilities for amorphous molecular solids that are composed of only a single type of chromophores was observed for the first time in amorphous ter(9,9-diarylfluorene)s. High hole and electron mobilities over 10-3 cm2/(V.s) can be achieved with these terfluorenes. In particular, the electron mobility observed represents the highest ever reported for amorphous molecular solids.
