An ambipolar organic field‐effect transistor (OFET) based on poly(diketopyrrolopyrrole‐terthiophene) (PDPPHD‐T3) is shown by P. Sonar, H. Haick, and co‐workers on page 4012 to sensitively detect xylene isomers at low to 40 ppm level in multiple sensing features. Combined with pattern‐recognition algorithms, a sole ambipolar FET sensor, rather than arrays of sensors, is able to discriminate highly...
An ambipolar poly(diketopyrrolopyrrole‐terthiophene)‐based field‐effect transistor (FET) sensitively detects xylene isomers at low ppm levels with multiple sensing features. Combined with pattern‐recognition algorithms, a sole ambipolar FET sensor, rather than arrays of sensors, can discriminate highly similar xylene structural isomers from one another.
