In article number 1701486 , Tsuyoshi Michinobu and co‐workers report on unipolar n‐channel organic transistors based on benzobisthiadiazole‐based semiconducting polymers. Replacing one sulfur atom in the benzobisthiadiazole unit with selenium leads to narrower bandgaps, deeper LUMO levels, and shorter lamellar packing distances, which produces the four‐fold higher electron mobility.
