Abstract

The prepn. of redox-responsive metallomacrocyclic ionophore I, which is easily obtained by the reaction of [(cymene)RuCl2]2 with 3-hydroxy-2-pyridone in the presence of Cs2CO3 or K2CO3, is described. The binding const. of the LiCl and the NaCl with I is comparable to that of high-affinity ionophores such as cryptands, and has a nearly perfect selectivity for Na+ over K+. Preliminary results indicate that structurally related metallacrown ethers having different arene ligands (e.g., C6Me6, C3H3Et3) instead of cymene can be assembled using the strategy described here. Since the selectivity of the ionophore is detd. by these ligands, redox-responsive receptors with designed specificities and solubilities can be envisioned. The crystal structure of I and its complex with Li and Na is detd

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
