The molecular packing of core-chlorinated naphthalene tetracarboxylic diimides (NDIs) shows various advantageous characteristics for charge transport including marginal core distortion, close π-plane distance, large π-orbital overlap, and high packing density. These features together with their easy processing and simple synthesis lead to thin-film transistor devices with excellent electron mobilities of up to 1.43 cm2 V−1 s−1 in air.
