文摘

In the paper, a highly selective aluminum ion fluorescent probe based on naphthalene derivate has been synthesized and characterized systemically. The probe molecule for aluminum ion exhibits excellent water solubility, and it shows strong blue fluorescence under ultraviolet light, which is attributed to the Photoinduced Electron Transfer (PET) process. In addition, the large association constant between probe and aluminum ion is 1.19 脳 10⁸ M^鈭?, which is obtained by fluorescent measurement. Moreover, the binding site of L with Al³⁺ is determined by ¹HNMR titration experiment.
