An ultrasensitive NO 2 sensor based on crystalline TIPS–pentacene films is achieved by Lifeng Chi and co‐workers in article number 1703192 , which has a sensitivity of more than 1000% per ppm, a fast response/recovery time, good reproducibility, and selectivity. The relationship between ultrahigh performance and film charge transport is studied and the films' low original carrier concentration and efficient charge‐transport ability are demonstrated to be key factors for the high performance.
