Chalcogen bridged pyrene derivatives: Synthesis, crystal−packing structures and field effect transistors properties

Abstract

To explore how the different intermolecular non-covalent interactions synergistically affect the molecular packing and properties when they existed at the same molecules. A series of new pyrene derivatives with chalcogen atoms as bridges were designed and synthesized. The single crystal structures of the compounds revealed the significant effect of different intermolecular non-covalent interactions on the molecular packing. The thin film transistor devices were fabricated and exhibit high mobility over 0.04 cm2 V−1 s−1. The distinct difference of the OFETs performance suggests that the intermolecular non-covalent interactions have very important effect on gearing the molecular packing and properties.
