A novel fluorescent chemodosimeter based on 1,8-naphthyridine exhibits high selectivity to Zn(2+) and Cu(2+). When 1-(7-acetamino-1,8-naphthyridyl)-2-(6-diacetaminopyridyl)ethene was mixed with CuCl2, hydrolysis of the acetamino group catalyzed by Cu(2+) complex was first observed. Resulting from coordination and hydrolysis catalyzed by the corresponding complex of Zn(2+) or Cu(2+), the highly effective fluorescent detection of Zn(2+) and Cu(2+) is realized with Zn(2+)-selective dual-emission and Cu(2+)-selective ON-OFF behavior.

基于1,8-萘啶的荧光化学计量仪，用于快速检测Zn2 +和Cu2 +。

基于1,8-萘啶的新型荧光化学计量器对Zn（2+）和Cu（2+）具有高选择性。当1-（7-乙酰氨基-1,8-萘基）-2-（6-二乙酰氨基吡啶基）乙烯与CuCl2混合时，首先观察到Cu（2+）配合物催化的乙酰氨基水解。通过相应的Zn（2+）或Cu（2+）配合物催化的配位和水解作用，通过Zn（2 +）-选择性实现了Zn（2+）和Cu（2+）的高效荧光检测双发射和Cu（2+）选择性的ON-OFF行为。
