Visual colorimetric and fluorescence turn-on probe for Cu(II) ion based on coordination and catalyzed oxidative cyclization of ortho amino azobenzene

2,2′-diaminoazobenzene (L1), a visual colorimetric and fluorescence turn-on detection probe for Cu2+ ion, has been discovered successfully. The yellow L1 solution changed into light-purple solution rapidly with dropping of Cu2+ ion observed by the naked eyes, for the formation of 1:1 complex of L1 and Cu2+ ion calculated by Job-plot method. Non-emissive L1 transformed into 2-(2-aminophenyl) benzotriazole (L1-BTA) with strong fluorescence at the peak around 475 nm, owing to the Cu2+ catalyzed oxidative cyclization of L1, accompanied by the fluorescence intensity gradually increasing within 20 min. And L1 was applied for quantitative detection of Cu2+ with good linear relationship between its UV absorbance and Cu2+ concentration, and exhibited high fluorescence selectivity toward Cu2+ over other metal ions (Fe3+, Zn2+, Cd2+, Co2+, Ni2+, Mn2+, Na+, Al3+ and Ca2+) in EtOH solution.

Fluorescent compounds containing benzotriazole, and preparation method and application of fluorescent compounds

The invention relates to fluorescent compounds containing benzotriazole as well as a preparation method and application of the fluorescent compounds. According to the preparation method, simple and easily available o-phenylenediamine compounds are used as a raw material and a Cu/Al-SBA-15 (I) mesoporous material with a synergistic effect of monovalent copper and framework aluminum is utilized so as to catalytically synthesize various fluorescent compounds containing benzotriazole. The key point of the invention is to provide a novel preparation method which enables the o-phenylenediamine compounds to be synthesized into a series of the benzotriazole-containing fluorescent compounds in a relatively short time and a relatively high yield under the catalysis of the Cu/Al-SBA-15 (I) mesoporous material with the synergistic effect of the monovalent copper and the framework aluminum. Meanwhile, the fluorescent compounds have stable cyclization structures and can be used as intermediates for organic synthesis to synthesize various luminous amide derivatives. The method has the advantages of simple and easily available raw materials, simple and controllable process, rapidness, high efficiency, few byproducts and easiness in industrial implementation.
