将氮杂冠醚[N，S，O]取代到呋喃并喹啉荧光团中，得到了一种新型的银离子比率荧光传感器--氮杂冠醚.紫外-可见吸收光谱和荧光发射光谱研究表明，与其它d（10）金属离子相比，冠醚在乙醇溶液中具有较大的Stokes位移（约173 nm）和红移（约50 nm），并与银离子具有较高的亲和力（log K = 7.21）.
Incorporating azacrown[N,S,O] into furoquinoline fluorophore yields a novel ratiometric fluorescent sensor FQ-crown for silver ions. UV-vis absorption and fluorescence emission investigations indicate that FQ-crown bears the features of a large Stokes shift, about 173 nm, and red-shift up to 50 nm in the emission spectra and high affinity for silver ions (log K = 7.21) in ethanol in comparison with other competitive d(10) metal ions.
