چکیده

A novel iridium(III) complex-based chemosensor bearing the 5,6-bis(salicylideneimino)-1,10-phenanthroline ligand receptor was developed, which exhibited a highly sensitive and selective color change from colorless to yellow and a visible turn-off luminescence response upon the addition of Cu(II) ions. The interactions of this iridium(III) complex with Cu2+ ions and thirteen other cations have been investigated by UV-Vis absorption titration, emission titration, and 1H NMR titration.

Label-free detection of sub-nanomolar lead(II) ions in aqueous solution using a metal-based luminescent switch-on probe.

A label-free oligonucleotide-based luminescent switch-on assay has been developed for the selective detection of sub-nanomolar Pb(2+) ions in aqueous solution and real water samples. An iridium(III) complex was employed as a G-quadruplex specific luminescent probe and a guanine rich DNA (PS2.M, 5'-GTG(3)TAG(3)CG(3)T(2)G(2)-3') was employed as recognition unit for Pb(2+) ions. The PS2.M exists i...

A colorimetric chemosensor for Cu2+ ion detection based on an iridium(III) complex

We report herein the synthesis and application of a series of novel cyclometalated iridium(III) complexes 1-3 bearing a rhodamine-linked NˆN ligand for the detection of Cu(2+) ions. Under the optimised conditions, the complexes exhibited high sensitivity and selectivity for Cu(2+) ions over a panel of other metal ions, and showed consistent performance in a pH value range of 6 to 8. Furthermore...

Luminescence switch-on assay of interferon-gamma using a G-quadruplex-selective iridium(III) complex.

In this study, we synthesized a series of 9 luminescent iridium(III) complexes and studied their ability to function as luminescent probes for G-quadruplex DNA. The iridium(III) complex 8 [Ir(pbtz)2(dtbpy)]PF6 (where pbtz = 2-phenylbenzo[d]thiazole; dtbpy = 4,4'-di-tert-butyl-2,2'-bipyridine) showed high selectivity for G-quadruplex DNA over single-stranded and double-stranded DNA, and was subs...

A Label-Free Luminescent Switch-On Assay for ATP Using a G-Quadruplex-Selective Iridium(III) Complex

We report herein the G-quadruplex-selective property of a luminescent cyclometallated iridium(III) complex for the detection of adenosine-5'-triphosphate (ATP) in aqueous solution. The ATP-binding aptamer was employed as the ATP recognition unit, while the iridium(III) complex was used to monitor the formation of the G-quadruplex structure induced by ATP. The sensitivity and fold enhancement of...
