Abstract

Dramatic emission change of PTZ a phenothiazine-based molecule with chloroform and different chlorinated hydrocarbons (CHCs) is providing an effective method for CHCs detection with naked eyes. The visual detection range can reach low concentration as low 30 mM in acetone and water for both volatile chloroform sensing and for liquid. Fabrication of one-time use paper sensors for volatile chloroform and glass-based sensors for liquid chloroform along with using a light source sun or solar box to allow on site detection of chloroform.
