Triphenylamine-based dicyano fluorophore for the selective detection of hydrazine vapor using cellulose acetate nanofibrous sheet.

ABSTRACT: A novel triphenylamine-based dicyano fluorophore (compound 2) was successfully synthesized using a Suzuki cross-coupling reaction, followed by a Knoevenagel condensation catalyzed with baker's yeast. Later, compound 2 was combined with the hydrazine vapor of an electrospun nanofiber sheet, depending on its solid condition. In addition, the electrospinning technique was used to create a nanofiber sheet made of cellulose acetate (CA) combined with compound 2. The resulting sheet had an average diameter of 250 ± 41 nm. The nanofiber sheet had a remarkable ability to detect and respond to hydrazine vapor in an aqueous solution. The concentration range of 0-0.08% w/v was accurately determined by analyzing fluorescence images using ImageJ software. The mechanism was confirmed by conducting a
