A pyrene-based sensor, named DBT (I), was synthesized through a one-step reaction and used as a ratiometric and fluorescent sensor for recognizing Al3+. The sensor showed high selectivity and sensitivity toward Al3+ relative to other competitive metal ions. DBT exhibited very weak fluorescence because of the photo-induced electron transfer process (PET). In the presence of Al3+, the emission of DBT at 451 nm enhanced owing to the coordination between DBT and Al3+ which hindered the PET. The detection of Al3+ by DBT was realized in a wide pH range of 5-12. The detection limits of Al3+ were 0.19 and 0.10 μM by ratiometric absorption (A360 nm/A342 nm) and fluorescent (F451 nm) methods, resp. Moreover, DBT was also successfully applied to detect Al3+ in practical water samples and solid phase (TLC plate). This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Safety of 2-Bromo-1-(pyren-1-yl)ethanone).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
