To rapid and efficient detection of TNP in water (TNP=2,4,6‐trinitrophenol), a pyrenyl‐based double‐charged probe PYPN was employed. The bright orange‐red emission of PYPN was seriously quenched upon the addition of TNP. The detection limit of PYPN for TNP is 0.218 μM. In addition, PYPN shows fast response rate (5 s) to TNP, good stability, excellent selectivity and anti‐interference (pH, anion, cation and other nitro compounds). Furthermore, PYPN can be used to rapidly detect TNP in various types of water samples. The rapid and efficient detection of TNP by PYPN may due to the electron and energy transfer as well as electrostatic interactions.

“…As for the fluorescence detection, it has obvious advantages such as easy operation, high selectivity, low sample destructiveness and visual detection, so it has been widely used. [24][25][26][27][28] In recent years, some compounds for fluorescently detecting TNP have been synthesized, mainly including triazine, fluorescein, naphthimide and other single fluorophore molecules, but the fluorescence intensities of the compounds containing single fluorophore are relatively weak, the fluorescence emission wavelengths are relatively small, and the TNP recognition effect is not significant. [29][30][31][32][33] Quinazolinone contains two nitrogen atoms, which has excellent conjugated structure and optical properties, and can be modified at multiple sites.…”

Substituent Effect: Synthesis of Three TNP‐Detecting Fluorescent Probes Based on Triazolothiadiazole‐Quinazolinone**

et al. 2022

Three novel fluorescent probes (QZLSZ‐1∼QZLSZ‐3) were designed and synthesized based on quinazolinone for comparing the representative substituent effects on QZLSZ fluorescence detection of 2, 4, 6‐trinitrophenol (TNP). The results show that the probes all exhibit high selectivity and good photo‐stability in wide pH rang and high quenching efficiency, indicating the rational structural design. Compared the substituent effects on the fluorescent properties of QZLSZ, it is found that electron ‐ donating group in QZLSZ‐1 is more favorable than the electron‐withdrawing group in QZLSZ‐3. The probe QZLSZ‐1 has the highest fluorescence quantum yield (0.5407) and the biggest Storks shift (191 nm). Furthermore, it has the lowest detection limit (0.16 μM), the optimal sensitivity (1.3 × 105 M−1), the largest detection range (10∼50 μM) and the rapidest response time (60 s) for the fluorescence recognition of TNP. The theoretical calculation results using Density functional theory (DFT) are highly consistent with that of the experiments. Particularly, QZLSZ‐1 has the best practical application value for qualitative and quantitative fluorescence detection of TNP in actual water samples.
