In order to improve device processability, it is important that organic semiconducting materials have good thermal durability. In article number https://doi.org/10.1002/aelm.201700142, Joon Hak Oh, Jeong‐Il Park, and co‐workers describe the synthesis and chargetransport behavior of a new thermally durable organic semiconductor, dibenzothiopheno[6,5‐b:6′,5′‐f]thieno[3,2‐b]thiophene (DPh‐DBTTT), using crystallographic analysis and an organic field‐effect transistor platform. Its outstanding electrical properties combined with thermal durability substantially extends the number of practical organic semiconductor applications.
