A truncated octahedral nanocage containing amide and quinoline groups has been synthesized as an artificial chemosensor for selectively fluorescent detection of uridine over other RNA-based nucleosides.

A simple fluorescent colorimetric chemosensor H2L for rapid detection of Cu 2+ has been developed. The LOD value towards was calculated to be 3.8 × 10 ?8 M. interactions between L and were studied by Job's plot, ESI-MS, DFT calculations single-crystal structure determination.

A novel fluorescent chemosensor containing a coumarin–thiourea unit and β- N-glycosyl moiety is designed, synthesized, characterized by 1 H NMR, 13 C elemental analysis. The can selectively efficiently detect Hg 2+ in CH 3 CN with detection limit of 2.6 μM.

Herein an anthracene-appended 2:3 copillar[5]arene was prepared by the CuAAC method, which was further used as a Fe(3+)-selective fluorescent chemosensor over a wide range of metal ions.

A new fluorescent chemosensor based on calix[4]arene bearing four iminoquinoline subunits on the upper rim was conveniently synthesized, which showed a remarkable enhanced fluorescent intensity in the presence of Cu(2+) ion and a high selectivity toward Cu(2+) ion over a wide range of tested metal ions in acetonitrile.

A new readily synthesized fluorescent chemosensor, calix[1]pyreno[3]pyrrole, displays excellent affinity with C(70). Anion-induced facile conformational changes and the dynamic nature of the receptor could be an excellent scaffold for sensing electron-deficient guests.

The fluorescent ligand (L) based on the N2S2 pyridinophane macrocycle and the 7-nitrobenzo[1,2,5]oxadiazole (NBD) fluorogenic fragment has been synthesized to coordinate Pd(II) ions. Loaded on dye-doped silica nanoparticles, L can be used as a ratiometric fluorescent chemosensor for Pd(II) in water with high selectivity toward other metal ions including the platinum group ones.

A novel fluoranthene based fluorescent chemosensor for the detection of picric acid (PA) at the parts per billion (ppb) level was evaluated. Static fluorescence quenching was the dominant process by intercalative π-π interaction between fluoranthene (S(1)) and nitroaromatics.

in this work, a novel hg2+ sensitive fluorescent chemosensor is constructed. the proposednano-chemosensor was prepared through the preparation of 3-(benzo[d]thiazol-2-yl)-7-hydroxy-2h-chromen-2-one functionalized silica nanoparticles which has high magnetization properties (btc-fe3o4@sio2). theûnal product was characterized by fourier transform infrared spectroscopy (ft-ir), thermal gravimetric...
