Highly Selective Turn-On Fluorescent Chemodosimeter for AlIII Detection through AlIII-Promoted Hydrolysis of C=N Double Bonds in the 8-Hydroxyquinoline Aldehyde Schiff Base

Fluorescent chemodosimeters based on small organic molecules are widely used in the detection of various analytes. However, chemodosimeters for metal ion detection are still limited to a few 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 emission at 487 nm based on inhibition of excited-state intramolecular proton transfer (ESIPT). Because of the specific catalytic ability of AlIII, the selectivity of 2 to AlIII is excellent both in aqueous solutions and in solid matrix. The fluorescence enhancement was as high as 582-fold and the turn-on fluorescence can be observed even by the naked eye upon an irradiation with a UV lamp. The detection limit of 2 for AlIII sensing is 54 nmol L?1 and the linear range is 0–50 μmol L?1. This work provides a new strategy for designing main-group-metal chemodosimeters based on small organic molecules.

Photochromatic compound, a method for its preparation, and articles which contain it

A photochromatic compound represented by the following general formula (I): STR1 where: R1 and R2 independently represent a linear, branched or cyclic C1-C10 alkyl radical, H, OH, F, Cl, Br, NH2, N(R4)2, COOH, OR4 or COOR4 where R4 is a C1-C10 linear, branched or cyclic alkyl radical, or an aryl radical; R3 is a variously substituted mono or polycondensed heterocyclic or aryl radical. A compound (I) demonstrates marked photochromatic characteristics both when in an organic solvent solution and when incorporated into polymer matrices.
