The electrical properties of organic semiconductors are strongly influenced by the electronic structure in the solid state. For DNTT derivatives, comparisons between experimental mobility values and theoretical predictions based on the hopping model reveal cases of exceptionally high mobility exceeding theoretical values and systems exhibiting reversed trends, suggesting the involvement of thermal effects such as dynamic disorder. This presentation focuses on the intrinsic mobility evaluation of diphenyl-DNTT isomers using single-crystal OFETs and discusses the impact of thermal fluctuations on the solid-state electronic structure through molecular dynamics simulations.
