“…180 The breadth of their applicability led Ding et al to design P61 (Figure 47a) as a potential NAC sensor. 181 P61 exhibited absorption at 270 nm and fluorescence emission at 392 nm, with a large Stokes shift (122 nm). In addition, the photophysical properties of P61 were evaluated in the presence of picric acid (TNP), 1,2-dinitrobenzene (1,2-DNB), 1,4dinitrobenzene (1,4-DNB), 2,4-dinitrochlorobenzene (2,4-DNT), 4-nitrochlorobenzene, 4-nitrobenzaldehyde, 2-nitrophenol (2-NP), 1,3-dinitrobenzene (1,3-DNB), and the nonnitro compound trihydroxybenzene (m-Thb) (Figure 47b).…”

Fluorescent and colorimetric sensors are important tools for investigating the chemical compositions of different matrices, including foods, environmental samples, and water. The high sensitivity, low interference, and low detection limits of these sensors have inspired scientists to investigate this class of sensing molecules for ion and molecule detection. Several examples of fluorescent and colorimetric sensors have been described in the literature; this Review focuses particularly on phenanthro [9,10d]imidazoles. Different strategies have been developed for obtaining phenanthro [9,10d]imidazoles, which enable modification of their optical properties upon interaction with specific analytes. These sensing responses usually involve changes in the fluorescence intensity and/or color arising from processes like photoinduced electron transfer, intramolecular charge transfer, intramolecular proton transfer in the excited state, and Forster resonance energy transfer. In this Review, we categorized these sensors into two different groups: those bearing formyl groups and their derivatives and those based on other molecular groups. The different optical responses of phenanthro [9,10-d]imidazole-based sensors upon interaction with specific analytes are discussed.

“…As one of the most common nitroaromatic explosives, 2,4,6trinitrophenol (TNP) possesses certain toxicity and hazard, which is an environmental pollutant. [1][2][3][4][5] Long term exposure to TNP can cause genovariation, anemia, and respiratory infection, even cause liver, eye, and kidney damage. [6][7][8][9] Moreover, soil and ground water in war territories are often contaminated with TNP to toxic levels, damaging for human health.…”

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.

“…1,2 Despite recent advances, the development of novel methods for the regiocontrolled synthesis of substituted imidazoles is of strategic importance. This is due to the preponderance of applications to which this important heterocycle is being deployed, such as the traditional applications in pharmaceuticals and agrochemicals 3,4 to emerging research into dyes for solar cells and other optical applications, [5][6][7][8][9][10][11][12][13][14][15][16] functional materials, 17 and catalysis 18 (Fig. 1).…”
