Triple-signaling mechanisms-based three-in-one multi-channel chemosensor for discriminating Cu2+, acetate and ion pair mimicking AND, NOR, INH and IMP logic functions

Chemosensor 1 shows three different responses towards Cu2+, acetate and Cu(OAc)2 ion pair at different wavelengths independently in its absorption and fluorescence behaviour following a triple-signaling mechanism, namely, internal ch

Coumarin-based urea-amide scaffold in ratiometric fluorescence sensing of CN?

Coumarin-based urea and urea–amide scaffolds 1–3 have been designed and synthesized for the selective and naked eye detection of cyanide ion. Of the three, compound 3 exhibits ratiometric fluorescence change selectively in the presence of CN? and validates the rationality in designing anion receptor. Upon interaction with CN?, the color of the solution of 3 in CH3CN under UV exposure becomes bright yellow, which is beneficial for its naked eye detection. Addition of CN? of ～10?4?M brings nice color change from colourless to yellow in ordinary light. The sensing event is supposed to be due to nucleophilic addition of CN? to the coumarin unit enabling intramolecular charge transfer (ICT) mechanism.

Triphenylamine-based simple chemosensor for selective fluorometric detection of fluoride, acetate and dihydrogenphosphate ions in different solvents

Triphenylamine-based new chemosensors 1 and 2 have been designed and synthesized for fluorometric detection of anions. The urea-amide conjugates in 1 and 2 are involved in binding of anions via hydrogen bonding. UV-vis and fluorescence titration experimen
