Selective sacrificial metal–organic frameworks: a highly quantitative colorimetric naked-eye detector for aluminum ions in aqueous solutions

Abstract

The detection, differentiation, and especially visual quantification of target compounds are important and interesting challenges for researchers.

A New Fluorescence MOF for Highly Sensitive Detection of Acetylacetone

“…Compared with various detection techniques, luminescent MOFs possess remarkable merits of rapid response, low cost, easy handing, high sensitivity and selectivity [11] . Numerous analytes including explosives, [12] oxoanion pollutants, [13] toxic anions, [14] cations, [15] small organic molecules, [16] biological molecules, [17] etc. have been determined by luminescent MOFs with high sensitivity and selectivity.…”

Effect of Proton Conduction on the Charge Storage Mechanism of a MOF as a Supercapacitor Electrode

“…The structural properties of MOFs, particularly their crystallinity, allow for optimizing molecular surface areas and tailoring their structural features for specific purposes. Furthermore, we can benefit from their porosity if the pores are filled with water or a nonvolatile proton carrier. − However, in most cases, MOFs are used as precursors or templates for deriving porous carbons via pyrolysis. , For direct use of MOFs, various modifications should be applied in their pore size, conductivity, and so forth. One way to enhance MOF conductivity is to fabricate a hybrid composite using materials with higher conductivity, such as graphene. , Another solution to improve the MOF conductivity is to design and construct proton-conducting MOFs. , …”

Electrochemical Applications of Ferrocene‐Based Coordination Polymers

“…[3] On the other hand, coordination polymers (CPs) are excellent precursors for the development of a new class of highly tailorable functionalized nanomaterials for gas storage, detection, catalysts, pollutant adsorption, and electrochemical applications. [4][5][6][7][8][9][10][11][12][13] CPs offer an endless variety of metal ion centers and connecting ligands (which can be redoxactive or -inactive and suitable for the construction of one-, two-, or three-dimensional networks), which is ideal for the construction of solid-state redox-active materials for diverse applications. Progress in the field of redox-active CPs is important for both fundamental and applied research, as these materials provide unique insights into charge transfer in the coordination space and exhibit features that may support the future development of useful apparatus.…”

“…The strong interaction between Fe(II) and the cyclopentadienyl rings endows Fc with good thermal stability and tolerance toward oxygen, thus facilitating the synthesis of various Fc derivatives [3] . On the other hand, coordination polymers (CPs) are excellent precursors for the development of a new class of highly tailorable functionalized nanomaterials for gas storage, detection, catalysts, pollutant adsorption, and electrochemical applications [4–13] . CPs offer an endless variety of metal ion centers and connecting ligands (which can be redox‐active or ‐inactive and suitable for the construction of one‐, two‐, or three‐dimensional networks), which is ideal for the construction of solid‐state redox‐active materials for diverse applications.…”
