Highly sensitive and selective colorimetric naked-eye detection of Cu2+ in aqueous medium using a hydrazone chemosensor

A new rhodamine-based colorimetric chemosensor for naked-eye detection of Cu 2+ in aqueous solution

“…On the other hand, Cu 2+ is not only a significant metallic pollutant, but also an essential element for living organisms. [3][4][5][6] So far, many progress has been achieved in the creation of a chemosensor for Cu 2+ , [7][8][9][10][11][12][13][14][15][16][17][18] however there is still room to develop easy-to-make, simple-to-use and observable colorimetric sensors for Cu 2+ in aqueous solution. Work related to this area is of great challenge and increasing interest.…”

Rhodamine B derivative-modified up-conversion nanoparticle probes based on fluorescence resonance energy transfer (FRET) for the solid-based detection of copper ions

“…Copper ion, as the third most abundant essential transition metal ion, plays a critical role in human health and environmental science, ranging from the diagnosis of life-threatening diseases to the analysis of environmental pollutants. [1][2][3] However, when the Cu 2+ ion is present at signicantly high or low concentrations, it leads to serious human diseases; 4,5 moreover, Cu 2+ is non-degradable and can accumulate in the environment; hence, Cu 2+ ion in excessive amounts will result in environmental pollution throughout the world due to its widespread use in industries, agriculture, household utensils, and water pipes. Therefore, the development of fast, convenient and reliable methods for the qualitative and quantitative detection of trace amounts of Cu 2+ ions is of signicant importance considering the biological and environmental implications of excess Cu 2+ ions.…”

New magnetic supported hydrazone Schiff base dioxomolybdenum (VI) complex: An efficient nanocatalyst for epoxidation of cyclooctene and norbornene

“…Since hydrazone ligands can induce various coordination numbers and geometries around metal center, they can react with a wide variety of transition metal ions . The hydrazone transition metal complexes have become increasingly popular class of complexes not only for their catalytic properties, but also for their usage in various fields such as pharmacology, sensors, nonlinear optics and electrochromism …”
