Chromoionophore VII (ETH 5418) is a lipophilic ionophore. [1] Visit our Sensor Applications portal to learn more. ETH 5418 was used for the designing of fluorescent microspheres. [2] …

2005年3月7日 · For ETH 5294 based sensing systems the emission peaks at 678 and 648 nm were used, while optodes containing ETH 5418/DiIC18 were characterized at 708 and 608 nm. All calibration curves were recorded in the range 10 −5 to 1 M of the primary ion concentration.

2008年9月10日 · Optode with ionophore and chromoionophore V exhibited good responses to silver ions from 10 −6 – 10 −1 M at pH 5.5. The proposed sensor showed high selectivity, good reproducibility and stability. With a different chromoionophore ETH 5418 the optode could response to copper (II) ions from 10 −6 – 10 −2 M.

2012年2月21日 · The absorption spectra of protonated and unprotonated ETH 5418 overlap the two emission peaks of upconverting material, respectively, which makes the inert nanorods ion-sensitive. Optodes for pH and metal ions (Na (+), K (+), Ca (2+), and Cu (2+)) were investigated and exhibited excellent sensitivity, selectivity, and reproducibility.

The absorption spectra of protonated and unprotonated ETH 5418 overlap the two emission peaks of the upconverting material, respectively, which allows the fluorescent ion sensing based on the inner filter effect. The proposed optodes exhibited highly selective and reproducible sensing property for measuring lead ions
