Solid-state organization of n-type carbazole-based semiconductors for organic thin-film transistors

Abstract

n-Type OTFTs were fabricated and characterised from a series of tricyanovinyl-substituted carbazole-based materials with different N-alkyl chain lengths as active layers. XRD studies gave insights into the main intermolecular interactions, molecular packing motifs and the degree of molecular order in thin films that justified the performance of the devices.
