Ligand functionalized copper nanoclusters for versatile applications in catalysis, sensing, bioimaging, and optoelectronics

“…Regarding organic compounds, Cu NC based sensors have been applied for detection of various medications including tramadol, 26 methotrexate, 51 carbamazepine, 52 nitrofurantoin, 42 o-phenylenediamine, 224 doxycycline, 25 and tetracycline; 225 biocidal and herbicidal compounds such as thiram and paraquat; 72 explosive compounds including trinitrotoluene (TNT), 71,226,227 mdinitrobenzene, 55 nitrofurantoin, 34 RDX, 27 and trinitrophenol (TNP); 19,228 food additives such as melamine, 229 folic acid, 56 quinoline yellow, 224 gossypol; 29 humidity and ethanol. 59 Representative examples are presented in Table 1 and are briefly outlined below. 4.2.1.…”

“…A dual-emitting film composed of GSH-Cu NCs and carbon dots (CDs) has been used by Wen et al 59 for the detection of atmospheric humidity in the range of 40-80%. The sensor was prepared through the infiltration of a CD solution in a filter paper followed by dipping in a Cu NC solution and then drying under vacuum.…”

Fluorescent Carbon Dots: Fantastic Electroluminescent Materials for Light‐Emitting Diodes

“…[ 27–30 ] These outstanding features endow CDs as excellent fluorescent nanomaterials with significant applications in bio‐imaging, theranostics, fluorescent sensing, photoelectric devices, and so on. [ 31–39 ]…”

Hydrothermal synthesis of blue‐green emitting carbon dots based on the liquid products of biodegradation of coal

“…Organic carbon sources used to obtain CDs are widely reported, which commonly include: biomacromolecules, organic small molecules, chain polymers, sugar compounds, amino acids, and so on. [42][43][44][45] The fluorescent CDs synthesized by organic carbon source will be obtained through dehydration and condensation and further carbonic. With the deepening of the research on CDs, biomass materials ubiquitous in nature and readily available are used to prepare CDs.…”

“…Thus, the fluorescence of CDs prepared by inorganic carbon sources is often generated because of the lack of effective transition energy levels. Organic carbon sources used to obtain CDs are widely reported, which commonly include: biomacromolecules, organic small molecules, chain polymers, sugar compounds, amino acids, and so on 42‐45 . The fluorescent CDs synthesized by organic carbon source will be obtained through dehydration and condensation and further carbonic.…”
