Luminescence ethylenediamine sensor based on terbium complexes entrapment

• We report a new luminescent material.
• The above materials were obtained by encapsulation of lanthanide complexes.
• Tb(acacn)@ZY displays obvious changes in luminescence colors.
• Tb(acacn)@ZY possess excellent selectivity and sensitivity for En vapor.
• Such a luminescent material represents a promising applications in En detection.

Ethylenediamine, as important chemical raw materials and fine chemical intermediates, has been widely applied in various industries. Detection of Ethylenediamine is highly desirable for a number of chemical industries due to its potential threat to human health. Chemical sensing bears an advantage over the traditional analysis method (liquid chromatography) owing to its sensing ability of visual inspection (such as the change in color, luminescence etc). Herein we report a new and solid luminescent material by encapsulating of terbium-acetylacetonate complexes within the cavities of Y type zeolite displaying obvious changes in luminescence colors triggered by solvent vapors, with excellent selectivity for En vapor.

Herein we report a new and solid luminescent material (Tb(acacn)@ZY) displaying obvious changes in luminescence colors triggered by solvent vapors, with excellent selectivity for En vapors. Obvious advantage of Tb(acacn)@ZY for the detection of En vapor is that we can observe the difference through visual inspection method. Such a luminescent platform represents a significant step forward to En detection.Figure optionsDownload as PowerPoint slide
