Article Description

A bi-functional colorimetric and fluorescent chemodosimeter PYCN has been designed and synthesized by the simple condensation of 1-pyrenecarboxaldehyde and 2,3-diaminomaleonitrile. In aqueous media, the chemodosimeter PYCN exhibits remarkably enhanced absorbance, a color change from yellow to colorless, and significant "off-on" fluorescence with blue emission in response to hypochlorite anions. Based on the ClO promoted de-diaminomaleonitrile reaction, the application of this dye as a ratiometric optical chemodosimeter for ClO has been investigated in detail.
