“…Over the last few years, Schipper and Jones groups have developed nanoring-shaped homometallic MCAs with different nuclearities for optically sensing several analytes. 191–195,197–199 Some remarkable examples include {Yb 14 } , {Yb 18 } , and {Nd 42 } for explosives sensing, {Nd 14 } , {Nd 18 } , and {Yb 18 } as antibiotics probes, {Nd 14 } for Cu 2+ , Co 2+ , H 2 PO 4− , and F − detection, {Eu 18 } and {Yb 18 } for anthrax biomarkers sensing. These MCAs highlight the potential that this class of compound holds in the sensors field.…”
