Exposure to even very low levels of lead, cadmium, and mercury ions is known to cause
neurological, reproductive, cardiovascular, and developmental disorders, which are more …

Coordination chemistry plays an essential role in the design of photoluminescent probes for
metal ions. Metal coordination to organic dyes induces distinct optical responses which …

Recently, the use of phosphorescent heavy-metal complexes as chemosensors has
attracted increasing interest due to their advantageous photophysical properties. This critical …

After a brief introduction on the main transduction mechanisms for metal ion detection by
fluorescence, this paper reviews ligand molecules containing fluorophores synthesized and …

Coumarin compounds represent an important type of naturally occurring and synthetic
oxygen-containing heterocycles with typical benzopyrone framework. This type of special …

The design and synthesis of a novel rhodamine spirolactam derivative and its application in
fluorescent detections of Cu2+ in aqueous solution and living cells are reported. The signal …

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 …
