“…1 On the other hand, light can be limited to one area (focusing on a specific area) and if the response is reversible, it can be easily turned on and off. 6 Azobenzenes, 13 spiropyrans, 14 spirooxazines, 15 diarylethanes, 16 and fulgides 17 are the photochromic compounds used in different polymeric systems. Rapid response to external stimuli and the relatively easy synthesis of the polymers containing spiropyran have led to the widespread application of this compound.…”

“…The multianalyte detection concept, which was first proposed by De Silva's group ( Magri et al., 2006 ; Schmittel and Shu, 2012 ; Chen et al., 2015 ; Magri, 2021 ), has become a hotspot in the field of sensors owing to its advantages of high efficiency, rapidity, simultaneous recognition and in-situ detection ( Xu et al., 2017 ; Park et al., 2018 ; Zhang et al., 2018 ; Chen et al., 2019a ; Zhao et al., 2021 ; Slenders et al., 2021 ; Huang et al., 2021b ; Nakamitsu et al., 2021 ). Multianalyte sensors were originally designed for multiple metal ions ( Magri et al., 2006 ), but these systems have subsequently been developed for multiple bioactive molecules ( Yin et al., 2018 ; Zhang et al, 2020b ; Thanzeel et al., 2020 ), bacteria ( Zheng et al., 2018 ), etc. In some cases, multifunctional sensors based on fluorescent gels ( Zhang et al., 2018 ; Ozay et al., 2020 ) or polymers ( Ozay et al., 2020 ; Liu et al., 2020 ; Huang et al., 2021a ) can simultaneously remove analytes, thus reducing the cost of pollutant treatment in practical applications.…”

Summary A series of N -alkyl-substituted polybenzimidazoles ( SPBIs ), synthesized by simple condensation and N -alkylation, act as functional materials with tunable microstructures and sensing performance. For their controllable morphologies, the formation of nano-/microspheres is observed at the n (RBr)/ n (PBI) feed ratio of 5:1. Products with different degrees of alkylation can recognize metal ions and nitroaromatic compounds (NACs). For example, SPBI-c , obtained at the feed ratio of 1:1, can selectively detect Cu 2+ , Fe 3+ , and NACs. By contrast, SPBI-a , obtained at the feed ratio of 0.1:1, can exclusively detect Cu 2+ with high sensitivity. Their sensing mechanisms have been studied by FT-IR spectroscopy, SEM, XPS, and DFT calculations. Interestingly, the SPBIs can adsorb Cu 2+ in solution and show good recyclability. These results demonstrate that polymeric materials with both sensing and adsorption applications can be realized by regulating the alkylation extent of the main chain, thus providing a new approach for the facile synthesis of multifunctional materials.

In this work, we introduce a highly selective and sensitive fluorescent sensor based on pyrene derivative for Fe(III) ion sensing in DMSO/water media. 2-(pyrene-2-yl)-1-(pyrene-2-ylmethyl)-1H-benzo[d]imidazole (PEBD) receptor was synthesized via simple condensation reaction and confirmed by spectroscopic techniques. The receptor exhibits fluorescence quenching in the presence of Fe(III) ions at 440 nm. ESI-MS and Job’s method were used to confirm the 1:1 molar binding ratio of the receptor PEBD to Fe(III) ions. Using the Benesi-Hildebrand equation the binding constant value was determined as 8.485×103 M-1. Furthermore, the limit of detection (LOD, 3σ/K) value was found to be 1.81µM in DMSO/water (95/5, v/v) media. According to the Environmental Protection Agency (EPA) of the United States, it is lower than the acceptable value of Fe3+ in drinking water (0.3 mg/L). The presence of 14 other metal ions such Co2+, Cr3+, Cu2+, Fe2+, Hg2+, Pb2+, K+, Ni2+, Mg2+, Cd2+, Ca2+, Mn2+, Al3+, and Zn2+ did not interfere with the detection of Fe(III) ions. Computational studies of the receptor PEBD were carried out with density functional theory (DFT) using B3LYP/ 6-311G (d, p), LANL2DZ level of theory. Finally, molecular docking studies have been performed to investigate the Cytochrome P450 1A1(CYP1A1) protein inhibitory action of the receptor PEBD.
