  • Highly Sensitive NH3 Detection Based on Organic Field-Effect

    Abstract. We have increased organic field-effect transistor (OFET) NH 3 response using tris (pentafluorophenyl)borane (TPFB) as a receptor. OFETs with this additive could detect concentrations of 450 ppb v/v, with a limit of detection of 350 ppb, the highest sensitivity reported to date for semiconductor films; in comparison, when triphenylmethane (TPM) or triphenylborane (TFB) was used as an additive, no obvious improvement in the sensitivity was observed.
