Sigma–hole interactions, in particular halogen bonding (XB) and chalcogen bonding (ChB),
have become indispensable tools in supramolecular chemistry, with wide-ranging …

Chemosensors possess significant importance in biological and environmental systems for
the detection of various chemical species. This review commences with a short description …

A selective sensor 1 for the fluorescent imaging of Cd2+ in living cells has been designed
and synthesized based on an internal charge transfer (ICT) mechanism. It can distinguish …

A fluorescent sensor, N-(quinolin-8-yl)-2-(quinolin-8-yloxy) acetamide (HL), based on 8-
aminoquinoline and 8-hydroxyquinoline platforms has been synthesized. This sensor …

A highly selective and sensitive OFF-ON fluorescent sensor 1, employing the PET
mechanism, was designed and synthesized. It could be used to detect Cd2+ ion in aqueous …

A novel tren-based tripodal chemosensor 1 bearing a rhodamine and two tosyl groups was
synthesized and its sensing behavior toward metal ions was investigated by UV/vis and …

A fluorescent sensor, QA, based on acetamidoquinoline with DPA as receptor, was
synthesized. In aqueous buffer solution, QA demonstrates high selectivity for sensing Cd2+ …

In a neutral aqueous environment, a new ratiometric Cd2+ fluorescent sensor 1a can
successfully discriminate Cd2+ from Zn2+ by undergoing two different internal charge …

Health or environmental issue caused by abnormal level of metal ions like Zn2+ or Cd2+ is a
worldwide concern. Develo** an inexpensive and facile detection method for Zn2+ and …

The metal ion complexing properties of the ligand DPP (2, 9-di-(pyrid-2-yl)-1, 10-
phenanthroline) were studied by crystallography, fluorimetry, and UV− visible spectroscopy …
