“…For example, the probes bearing cucurbit [10]uril or dicyanomethylene-4H-chromene moieties were of obvious color change when silver ion was held. [29][30] Also, a highly selective turn-on-type of probe bearing indole moieties for silver ion was developed by Zhang et al [31] Even so, developing more convenient and effective method of detection for dihydrogen phosphate or silver ion is still desired.…”

A new near-infrared fluorescence sensor PDI-PD for Ag + ions was successfully prepared and its structure characterized by 1 H nuclear magnetic resonance (NMR), 13 C NMR and high-resolution mass spectrometry; matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (HRMS MALDI-TOF). The probe exhibited rapid, sensitive, and selective two-channel fluorescence responses towards Ag + ions and protons. The probe has a marked high binding affinity and high sensitivity for Ag + , with a detection limit of 1.4 × 10 −6 M. An approximately five-fold enhanced core emission at 784 nm was attributed to fluorescence resonance energy transfer (FRET). The enhanced core emission of the probe with Ag + ions based on photo-induced electron transfer and FRET is discussed. In addition, the probe presented a visible colour change. All experimental results demonstrated that PDI-PD is an efficient tool for the selective, sensitive and rapid detection of Ag + ions and protons using two-channel fluorescence responses.

The salicylaldehyde-functionalized cyclotriphosphazene (1) and thiophene appended cyclotriphosphazene based Schiff base (2) were designed and synthesized. The characterizations were carried out via MALDI-TOF, FTIR, 13 C, 31 P and 1 H NMR. The photophysical behavior of compound 2 was evaluated by UV-Vis absorption, time-resolved fluorescence, excitation-emission matrix (EEM) analysis, steady-state fluorescence, and 3Dfluorescence spectroscopies. Compound 2 demonstrated selective fluorescence "turn-on" response at 427 nm towards to Ag + ion when the tested competitive species did not affect fluorescence signal. The binding and sensing mechanisms were evaluated by DFT calculations which approved that the PET process between C=N and fluorophore groups was inhibited, and the fluorescence "turn-on" response was obtained with the contribution of CHEF after 1 : 1 coordination of compound 2 with Ag + ion. The LOD and LOQ were calculated as 3.15 and 9.45 μmol L À 1 , respectively in the linear range of 9.35-210.00 μmol L À 1 Ag + ions. The practical application of compound 2 for Ag + determination was successfully performed in environmental waters after optimization of measurement conditions. The obtained results approved that compound 2 is a selective fluorescent sensor for Ag + ions and it can be used for spectrofluorimetric Ag + determination in real samples. Importantly, according to the literature, this report is the first example of cyclotriphosphazene based fluorescent sensor for Ag + ion.
