Organic thin-film transistor (OTFT)-based gas sensors, the promising candidates of electrical sensing, have received particular attention owing to their intrinsic advantages in low-cost and portage applications in chemical, biological, and physical monitoring. Gas sensing is in general important for environment and health issues. we report, here, p-type conjugated polymers containing different side-chains on diketopyrrolopyrrole (DPP)-cores showing high hole mobility. Gas sensing properties were measured upon exposure to ammonia gas. We observed that a gradual negative shift in the transfer curves increased with exposure time and concentration of ammonia gas. |
