Abstract

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. Abstract : The development of new organic semiconductors has been mainly led by the search for new π-conjugated cores, but recently the use of flexible side chains is attracting more and more attention to control the molecular packing and order in the solid state to improve the charge-transporting properties. In this work, the charge transport properties of a series of tricyanovinyl-substituted carbazole-based materials with different alkyl chain lengths have been investigated and correlated with the respective intermolecular interactions and molecular packings via X-ray diffraction (XRD) studies.
