A selective bis-thiophene chalcone-based spectrofluorimetric sensor for Fe.

A highly selective bis thiophene-based chalcone as a chemosensor for detecting Fe metal ions in DMF: HO (9:1). This sensor was selective toward ferric ions over other metal ions with a detection limit in micromolar range.

A Review on Metal Ion Sensors Derived from Chalcone Precursor.

Disclosure of new molecular probes as chromogenic and fluorogenic cation sensors is scientifically exigent work. Recently chalcone derivatives gained more attention because of their structural variability. A suitable donor and acceptor groups separated by delocalized π-orbitals display excellent chromogenic and fluorogenic properties because of intramolecular charge transfer (ICT).

A Comprehensive Review on Thiophene Based Chemosensors.

The recognition and sensing of various analytes in aqueous and biological systems by using fluorometric or colorimetric chemosensors possessing high selectivity and sensitivity, low cost has gained enormous attention. Furthermore, thiophene derivatives possess exceptional photophysical properties compared to other heterocycles, and therefore they can be employed in chemosensors for analyte detection. In this review, we have tried to explore the design and detection mechanism of various thiophene-based probes, practical applicability, and their advanced models (design guides), which could be thoughtful for the synthesis of new thiophene-based probes.
