“…Furthermore, the authors demonstrated that P46 could be used for the detection of H 2 S in MCF-7 cells using the same sequential on–off–on process. Highly sensitive and selective fluorescent sensors toward Cu 2+ based on phenanthro[9,10- d ]imidazoles have been recently reported indicating not only the continuous efforts to monitor and quantify this cation in the environmental and biological systems but also their ability as an optical sensor. − …”

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.

“…Among various detection techniques for Al ions, fluorescence-based sensors have attracted much attention because of their high sensitivity and selectivity, low detection limits, simple operation, and possible real-time monitoring with fast response [8][9][10][11][12][13]. Recently, a number of efficient fluorescent sensors have been reported for Al ion detection [14][15][16][17][18].…”

Though 2,5-dihydroxyterephthalic acid (DHT) is composed of a single benzene molecule, it is blue-emissive in common organic solvents and in the solid state. Like most organic fluorophores, DHT is not soluble in water, which limits its versatile use in metal ion detection in an aqueous medium. To improve the water solubility of DHT and its use as a molecular sensor in aqueous solutions, its deprotonated form, DHT-K, was synthesized through the simple one-pot reaction of DHT with KOH. Compared with DHT, DHT-K was highly soluble in water and emitted yellow fluorescence in the solution and the solid. In addition, DHT-K showed high selectivity for Al ions, exhibiting fluorescence wavelength changes from 540 to 495 nm depending on the Al ion concentration. A linear relationship between the fluorescence intensity of DHT-K and Al ion concentration was established ranging from 18.96 to 247 μM with a detection limit of 1.84 µM. The binding stoichiometry between DHT-K and Al ions was determined by Job’s plot and found to be 1:2. Upon exposure to Al ions, DHT-K showed significant changes in fluorescence color and emission wavelength, whereas no fluorescence changes were observed by the addition of various metal ions such as Zn2+, Mg2+, Ca2+, Cu2+, Fe3+, and Co2+. Thus, DHT-K can be applied as a fluorescent sensor that can selectively detect Al ions in aqueous solutions.
