Abstract

Exposure of hydrazine vapor to conjugated-polymer films reduces the small no. of oxidized trap sites that quench excitons. This scheme is effective for trace hydrazine detection with a detection limit of <1 ppm. The introduction of an oxidizing dopant quenches the polymer emission and permits detection of hydrazine with larger on/off ratios. [on SciFinder(R)]
