“…A single molecular sensor for multiple analytes can be designed and synthesized by organizing its various functionalities compatible to the size and shape of the analyte [8]. Amongst the various anions, Iion is one of the most biologically essential anion owing to its pronounced utility in sustaining neurological activity and thyroid gland function [9][10]. However, very few examples of I -sensing fluorescent chemosensors have been reported because of its large size and weaker basicity than the other halides (F -, Cl -and Br -).…”

A new C 3v -symmetric homooxacalix[3]arene L bearing pyrene moieties as fluorophore has been designed and synthesized. L exhibits a significant fluorescence quenching responses to I − even in the concurrent presence of other potentially competing anions. There is a good linear relationship between the fluorescence intensity and the concentration of I − ranging from 0 to 100 μM and the detection limit was calculated to be as low as 164 nM. The ligand L can be served as fluorescent chemosensor for highly selective, sensitive, and rapid detection of I − .

The synthesis and pH‐sensing property of a novel phenalenone‐based compound, 9‐(4‐hydroxyphenylamino)‐1‐oxo‐phenalenone (HPAP), is reported. The newly synthesized compound is capable of functioning as a pH sensor in the region of pH 7 to 12. The sensor can be used as a colorimetric indicator in the transition from pH 10 to pH 11. The sensor is able to function in four detectable channels. All four channels (UV, emission, colorimetric/visible and photoluminescence) have been shown to be reversible, thus implying the reuse of this single‐molecule sensor and indicator for several experiments. Mechanistic investigations have been performed by UV, NMR and DFT studies which indicate that a photoinduced electron transfer (PET) based mechanism could be operative. Straightforward and cost‐effective application of the sensor in thin‐layer chromatography has also been established.
