Description
Abstract
A comparative study of carbazolocarbazole isomers and their respective N-alkyl derivatives confirms the good performance of carbazolo[2,1-a]carbazole as hole transporting material in organic field effect transistors. The azaphenacene structure of this molecule forms a dense packing promoted by particularly short longitudinal shifts between molecules establishing face-to-face and edge-to-face interactions. Computational calculations have determined an almost isotropic 2D transport environment within a lamellar structure. This favorable solid state arrangement, in combination with appropriate interfacial layers, has led to a high mobility (1.3 cm2V-1s-1) that validates the aptitude of this molecular material as organic semiconductor.
