Abstract

Hole drift mobility of poly(dibenzofulvene) was found to be 2.7 × 10−4 cm2V−1s−1 at 299 K at a field strength of 7 × 105 Vcm−1 by the time-of-flight (TOF) measurement on a cast film containing 2,4,7-trinitrofluorenylidene-9-malononitrile as an electron acceptor. This value is higher than that of main-chain π-conjugating poly(π-phenylenevinylene) (1 × 10−5 cm2V−1s−1), is comparable to that of main-chain σ-conjugating poly(methylphenylsilane) (1 × 10−4 cm2V−1s−1), and is slightly lower than that of Se (10−4 cm2V−1s−1 order), an inorganic semiconductor.
