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.
