Highly selective and sensitive fluorescent zeolitic imidazole frameworks sensor for nitroaromatic explosive detection

The encapsulation of ZnQ into ZIF-8 allows fluorescent and colorimetric detection of nitroaromatic explosives, such as 2-4-6 trinitrotoluene (TNT). These are dangerous materials that pose safety and environmental risks.

Organic Photochromic Compounds

An organic photochromic compound is explored as a new portable colorimetric sensor for nitroaromatics. This photochromic compound switches from colourless to pink upon exposure to ultraviolet light. In the presence of nitroaromatic explosive derivatives the photoswitching behaviour of the dithienylethene is suppressed, while a potential false positive (toluene) has little effect. The degree of photoswitching inhibition was determined by comparing the integrated visible absorption with the concentration of the analyte to give the pseudo Stern–Volmer constant (KPSV). The KPSVs measured varied from 12900 (p-nitrotoluene) to 236 M–1 (toluene), which were directly related to the analyte absorption at the excitation wavelength.
