Two-dimensional materials have been widely studied for their thickness-dependent physical and chemical properties. These materials have a large surface-to-volume ratio, allowing for easy functionalization, making them suitable for chemical sensors. In this study, two types of 2D metal-organic frameworks based on functionalized anthracene derivatives were synthesized and used as sensors for Fe3+ and ascorbic acid at low concentrations.
Two-dimensional (2D) materials are newly developed for their thickness-dependent physical and chemical properties. The major characteristic of this type of material is that the planar structure flaunts a large surface-to-volume ratio, thereby providing a platform for straightforward and easy functionalization with chemical moieties, which prompting us to use it as a chemical sensor. We designed and synthesized two types of 2D metal-organic frameworks based on the functionalized anthracene derivative 4,4 '-(anthracene-9,10-diylbis(ethyne-2,1-diyl))dibenzoic acid (H2L), [Pb(L)(DMF)] (denoted as Pb-MOF) and [Sm(L)(HCO2)(DMF)] (denoted as Sm-MOF). These two materials are great sensors for probing Fe3+ and ascorbic acid (AA) with the low concentration according to color-change recover effect. Fe3+ was captured by MOF and this quenching mechanism was investigated using luminescence, UV-vis, XPS, and lifetime studies.
