“…Hence, there is a need for monitoring devices to measure the iron level in the environment. [4,5] The US Environemantal Protection Agency and the World Health Organization have set a tolerance limit of 0.3 mg/L for iron concentration in drinking water. [6,7] Many fluorescent molecular devices have been developed in recent decades, most of which have been based on fluorescent quenching mechanisms due to the paramagnetic character of iron.…”

The synthesis of a novel, and highly selective Fe3+ ion sensor based on anthrone‐spirolactam and its quinoline hybrid ligand is reported. The designed ligand displayed selective detection of Fe3+ ions with enhanced fluorescence emission. The complexation of Fe3+ ion led to a red shift of 32 nm from 420 nm to 452 nm, and a several fold increase in intensity with fluorescent green emission. The complexation (detection) of Fe3+ ions with ligand resulted in chelation enhanced fluorescence and intramolecular charge transfer through the inhibition of C=N isomerization. This hybrid sensor shows high sensitivity and selectivity, spontaneous response, and works on a wide pH range a minimum detection limit of 6.83 × 10−8 M. Importantly, the sensor works through the fluorescence turn‐on mechanism that overcomes the paramagnetic effect of Fe3+ ions. The binding mechanism between the ligand and the Fe3+ ions was established from the Job's plot method, optical studies, Fourier transfor infrared spectroscopy, NMR titration, fluorescence life‐time studies, and density functional theory optimization. The sensor displayed excellent results in the quantification of Fe3+ ions from real water samples. Furthermore, due to its biocompatibility nature, fluorescent spotting of Fe3+ ions in live cells revealed its bioimaging applications.

A new indole-based compound N-(pyridine-2-ylmethyl)-1Hindole-2-carboxamide (FL) which could selectively recognize Al 3 + had been designed, synthesized and evaluated. FL could detect Al 3 + with high sensitivity. The fluorescence intensity of FL-Al 3 + solution was linear dependence to the concentration of Al 3 + in the ranges from 0 to 5 μmol/L. The addition of Al 3 + caused quenching of fluorescence intensity and the limit of detection for Al 3 + was as low as 1.79 × 10 À 9 M. The binding ratio of FL-Al 3 + was obtained 3:2 by Job's plot and the binding constant was 9.37 × 10 5 . Moreover, FL had been successfully applied in real sample detection.[a] J.
