A pyrene derivative has been synthesized as a visible light excitable fluorescent chemodosimeter which exhibits “on–off” and “green–red” fluorescence behavior for Ni²⁺ and Pb²⁺ with different reaction speed, respectively, and its sensing ability toward metal cations and counter ions was investigated in detail. The high selectivity of the ‘in situ’ prepared Ni²⁺ and Pb²⁺ complexes toward EDA and the reaction speed difference provide two new effective methods for distinguishing between Ni²⁺ and Pb²⁺.

Ni ²⁺ / Pb ²⁺的可见光激发“开-关”和“绿-红色”荧光化学计量仪†

derivative衍生物已合成为可激发可见光的荧光化学计量仪，在不同的反应速度下，Ni ²⁺和Pb ²⁺分别表现出“开-关”和“绿-红”荧光行为，并且对金属阳离子的感测能力强并详细研究了抗衡离子。“原位”制备的Ni ²⁺和Pb ²⁺配合物对EDA的高选择性和反应速度的差异为区分Ni ²⁺和Pb ²⁺提供了两种新的有效方法。
