Abstract
A Naphthalene diimide (NDI)-incorporated helical thienoacene was developed. The compound has high electron mobility (1.4 cm2 V-1 s-1) thanks to its two-dimensional π-π interaction assisted by the intermolecular C-HO hydrogen bonding of the NDI moieties. Moreover, its bow-shaped π-skeleton reduces molecular fluctuation and gives the compound a thermally stable solid phase, which enables us to fabricate thermally stable organic devices.
