Ambipolar charge transport of TIPS-pentacene single-crystals grown from non-polar solvents†
Abstract
Charge transport of solution-grown TIPS-pentacene single-crystals depends on the polarity of the used solvents. Crystals grown from non-polar solvents exhibit ambipolar transport (μe 0.020 cm2 V−1 s−1; μh 5.0 cm2 V−1 s−1), while polar solvents suppress electron transport. This work indicates that appropriate selection of solvents should further harvest the n-type behaviors of organic semiconductors.
