A highly specific chalcone derivative grafted ethylcellulose fluorescent probe for rapid and sensitive detection of Al3+ in actual environmental and food samples

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.…”
