Gas sensors based on organic field‐effect transistors (OFETs) may enable a broad range of monitoring applications. Growth of ultrathin and microstructured organic semiconductor film is an efficient way to realize high performance OFET‐based sensors. On page 3419, Lifeng Chi, Klaus Müllen and co‐workers demonstrate high performance OFET‐based ammonia sensors with ultrathin (4‐6 molecular layers) dendritic...
High performance organic field‐effect transistor (OFET)‐based ammonia sensors are demonstrated with ultrathin (4–6 molecular layers) dendritic microstripes of an organic semiconductor prepared via dip‐coating. These sensors exhibit high sensitivity, fast response/recovery rate, good selectivity, low concentration detection ability, and reliable reversibility, as well as stability. Such a performance...
