A pyridyl based Schiff base compound, (1E,1′E)‐N,N′‐(butane‐1,4‐diyl)bis(1‐(pyridin‐2‐yl)methanimine) (2pdab) was observed to serve as a highly selective and sensitive ratiometric chemosensor for Ni2+ and Cd2+ ions. Mole ratio method and Yoe Jone's method showed a 1:1 binding mode of metal ions (Ni2+ and Cd2+) with 2pdab, while a binding constant of 26.88 ×106 L/mol and 4.29×106 L/mol, for Ni2+ and Cd2+, respectively, was determined. The limit of detection of 2pdab in sensing Ni2+ and Cd2+ was observed to be 3.08 μM and 1.4688 μM, respectively. The selectivity of 2pdab to detect Cd2+ and Ni2+ among various other competitive ions was also studied. The sensor, 2pdab, was applied in real time application for detection of nickel ion in river water sample.

“…Accordingly, the development of a novel colorimetric chemosensor for the rapid and convenient detection of Ni 2+ and Fe 3+ is attractive. The binding behaviour of receptor (HQNM) [ 18 ] has already been established, hence, in this article, we are discussing more about DHQ and its sensing behaviour with different cations.…”

“…The UV-visible spectrum of the receptor HQNM [ 18 ] with Ni 2+ is characterized by two bands centred at 340 and 442 nm ( figure 1 ). As shown in figure 1 a , upon gradually increasing the nickel ion concentration, the band at 340 nm gradually weakens and a new band appears at 442 nm with an isosbestic point at 370 nm.…”

Single-crystal X-ray structures of dimeric quinoxaline aldehyde (QA), quinoxaline dihydrazone (DHQ) and HQNM (Goswami S et al. 2013 Tetrahedron Lett. 54, 5075–5077.

Chem. 38, 6230–6235. (doi:10.1039/C4NJ01498G10.1039/C4NJ01498G)) are reported along with the theoretical study. Among them, QA is not acting as an active probe, but DHQ and HQNM are serving as selective and sensitive probe for the Fe3+ cation and the Ni2+ cation, respectively. DHQ can also detect the Fe3+ in commercial fruit juices (grape and pomegranate).

Quinoxaline-based novel acid-responsive probe Q1 was designed on the basis of a conjugated donor-acceptor (D-A) subunit. Q1 shows colorimetric and fluorometric changes through protonation and deprotonation in dichloromethane. With the addition of the trifluoroacetic acid (TFA), UV-vis absorption spectral changes in peak intensity of Q1 was observed. Moreover, the appearance of a new peaks at 284 nm 434 nm in absorption spectra with the addition of TFA indicating protonation of quinoxaline nitrogen and form Q1.H+ and Q1.2H+. The emission spectra display appearance of new emission peak at 515 nm. The optical property variations were supported by time resolved fluorescence studies. The energy band gap was calculated by employing cyclic voltammetry and density functional calculations. Upon addition of triethylamine (TEA) the fluorescence emission spectral changes of Q1 are found to be reversible. Q1 shows color changes from blue to green in basic and acidic medium, respectively. The paper strip test was developed for making Q1 a colorimetric and fluorometric indicator.
