A novel dehydroabietic acid-based AIE-active fluorescent probe for rapid detection of Hg2+ and its environmental and biological applications

A Convenient Way to Quinoxaline Derivatives through the Reaction of 2-(3-Oxoindolin-2-yl)-2-phenylacetonitriles with Benzene-1,2-diamines

“…Many quinoxaline-based natural products have shown a broad range of bioactivities [ 6 , 7 ] and naturally, this heterocyclic core is considered one of the privileged pharmacophoric scaffolds for drug design [ 8 ]. In some cases, those compounds were successfully employed as efficient fluorescent probes used in molecular electronics, analytical chemistry, and the design of photo-triggered medicines [ 9 , 10 , 11 ] while quinoxalines 4 bearing ortho-aniline moiety at C-2 (or their closely related derivatives) has attracted great attention as selective DNA triple- and quadruple-helix intercalating ligands [ 12 , 13 , 14 , 15 , 16 , 17 ]. Nowadays, many synthetic approaches to these structures have been developed, although most of them rely on multi-step functional group transformation sequences.…”

Recent advances in fluorescent materials for mercury(ii) ion detection

“…Besides, Liu et al 107 had reported another mechanism for Hg 2+ ion detection based on AIE phosphors. They prepared a novel dehydroabietic acid derivative with a quinoxaline moiety (denoted as DBAQ).…”

Sustainable production of carbazole-based BioAIEgens from lignin major motifs

“…AIE luminogens 21–23 either derived from biomass or possessing natural skeletons (referred to as BioAIEgens) have drawn great attention owing to the advantages of high biocompatibility, their green nature and renewability. 24–32 Notably, BioAIE materials feature enhanced conjugation or aromatic structures, which facilitate fluorescence emission. 33 Given lignin's inherent fluorescence stemming from its abundance of aromatic rings and carbonyl groups, 34 renewable lignin resources present an ideal starting point for producing bio-based AIE optical materials.…”
