A multifunctional aggregation-induced emission (AIE)-active fluorescent chemosensor for detection of Zn2+ and Hg2+ was written by Tang, Aling;Yin, Ya;Chen, Zhao;Fan, Congbin;Liu, Gang;Pu, Shouzhi. And the article was included in Tetrahedron in 2019.COA of Formula: C12H7BrN2 This article mentions the following:
An aggregation-induced emission (AIE)-active fluorescent chemosensor based on a tetraphenylethene (TPE) unit was successfully designed and synthesized. The luminogen could detect Zn2+ selectively in a THF solution with the detection limit of 1.24 鑴?10-6 mol L-1. Meanwhile, the luminogen could also detect Hg2+ selectively in a THF-water mixture with the water content of 90%, and the detection limit was 2.55 鑴?10-9 mol L-1. Also, the solid-state mechanochromic fluorescence behavior of the luminogen was studied systematically. Indeed, the AIE-active luminogen also exhibited reversible mechanofluorochromic phenomenon involving fluorescent color change from blue to green, and powder x-ray diffraction results indicated that the switchable morphol. conversion between crystalline and amorphous states was responsible for this mechanochromism phenomenon. In the experiment, the researchers used many compounds, for example, 2-Bromo-1,10-phenanthroline (cas: 22426-14-8COA of Formula: C12H7BrN2).
2-Bromo-1,10-phenanthroline (cas: 22426-14-8) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.COA of Formula: C12H7BrN2
