Highly Selective Turn-On Fluorescent Chemodosimeter for Al<sup>III</sup>
Detection through Al<sup>III</sup>
-Promoted Hydrolysis of C=N Double Bonds in the 8-Hydroxyquinoline Aldehyde Schiff Base
transition metals, such as HgII, CuII, FeIII, AuIII, etc. In this work, a fluorescent chemodosimeter of 5‐chloro‐7‐phenyliminomethyl‐8‐hydroxyquinoline (2) for the detection of AlIII is reported. Chemodosimeter 2 exhibits a turn‐on fluorescence response to AlIII owing to an AlIII‐promoted hydrolysis of carbon–nitrogen double bonds. This reaction yielded a 1–Al complex, which exhibited high fluorescence

A series of naphthaldehyde‐2‐pyridinehydrazone derivatives were discovered to display interesting ‘turn‐on’ fluorescence response to Zn2+ in 99% water/DMSO (v/v) at pH 7.0. Mechanism study indicated that different substituent groups in the naphthaldehyde moiety exhibited significant influence on the detection of Zn2+. The electron rich group resulted in longer fluorescence wavelengths but smaller fluorescence
