The aromatisation of 7-diethylamino-3,4-dihydrocoumarin provides an alternative fluorescent probing technique to selectively detect the concentration of superoxide anion in solution. In addition, we reported the advantage of evaluating O2- sensing probes

A series of water-soluble encapsulated copper(I), silver(I) or gold(I) complexes based on NHC-capped permethylated cyclodextrins (ICyDMe) were developed and used as catalysts in pure water for hydration, lactonization, hydroarylation and cycloisomerization reactions. ICyDMe ligands gave cavity-based high regioselectivity in hydroarylations, and high enantioselectivities in gold-catalyzed cycloisomerizations reactions giving up to 98 % ee in water. These ICyDMe are therefore useful ligands for selective catalysis in pure water.
Synthesis and fluorescent properties of coumarin-benzimidazole and coumarin–phenanthroimidazole hybrids
Fan, Hongli,Wang, Lingqiang,Wang, Xiaolong
, p. 9 - 13 (2019/11/13)
Two coumarin-benzimidazole hybrids and two coumarin-phenanthroimidazole conjugates were conveniently synthesized and characterized. The UV–vis absorption, emission spectra, absolute quantum yields, and fluorescence lifetimes of these compounds in diluted dichloromethane solutions were measured.
