Azo Dye-based Optical Probe for the Detection toward Mimic Molecule of Date Rape Drug

Abstract The azo dye-based visual responsive optical probe 5-(diheptylamino)-2-((3,5-dinitrothiophen-2-yl)diazenyl)phenol (DP), for the purpose of detection toward the mimic molecule of date rape drug was designed, synthesized and characterized. The recognizing abilities toward the mimic molecule (sodium butyrate) of date rape drug (gamma-hydroxybutyric acid) were examined in water. The prepared molecule was visually, analytically, and theoretically confirmed with the sensing ability of the probe. Developing an easy-to-use sensor kit will work spontaneously with a detectable colorimetric response in daylight. Obtained color change from light turquoise color to bluish-purple toward sodium butyrate containing alcoholic beverages was successfully recognized and confirmed. Even though the color change from light turquoise to bluish-purple obtained, which is not easily recognized clearly with the eye under normal light, UV- Visible spectra indicate the changes, thus the probe can be utilized productively to protect the victim from sexual assault.
