An exploratory study on a group of silylethynylated N ‐heteropentacenes as soluble and stable organic semiconductors is presented. An interesting finding is that a silylethynylated N ‐heteropentacene can function as a p‐type, n‐type, or ambipolar organic semiconductor depending on the structure of its π ‐backbone. The tetraazapentacene derivative is one of the best performing n‐type organic semiconductors with an electron mobility of up to 3.3 cm 2 V −1 s −1 .
