Abstract

Tetracenothiophene derivatives are disclosed, which comprise alkoxy-C-alkyne solubilizing groups at transversal positions of the tetracenothiophene unit. These compounds enable preferential molecular stacking and a high field effect mobility and at the same time show improved solubility as compared to known benzothiophene- and pentacene-based materials. In addition, organic thin films comprising these derivatives, their use in electronic devices and components, such as organic thin film transistors, and methods of manufacturing the same are disclosed.
