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

The complete remediation of extremely toxic elements, such as cadmium, must be achieved
to control the various stages in their life cycles, from mining as virgin ore to using them as …

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 …
