Abstract

AbstractConjugated small molecules are advanced semiconductor materials with attractive physicochemical and optoelectronic properties enabling the development of next‐generation electronic devices. The charge carrier mobility of small molecules strongly influences the efficiency of organic and hybrid electronics based on them. Herein, we report the synthesis of four novel small molecules and their investigation with regard to the impact of molecular structure and thermal treatment of films on charge carriers’ mobility. The benzodithiophene‐containing compounds (BDT) were shown to be more promising in terms of tuning the morphology upon thermal treatment. Impressive enhancement of hole mobilities by more than 50 times was found for annealed films based on a compound M4 comprising triisopropylsilyl‐functionalized BDT core. The results provide a favorable experience and strategy for the rational design of state‐of‐the‐art organic semiconductor materials (OSMs) and for improving their charge‐transport characteristics.
