A novel 2D metal–organic framework probe: a highly sensitive and visual fluorescent sensor for Al³⁺, Cr³⁺ and Fe³⁺ ions

Abstract

The development of metal-organic frameworks (MOFs) based fluorescence sensors in detection of metal ions attracted significant interests. In this study, a novel 2D MOF Tb-DBA was constructed using Tb3+ and...

Facile synthesis of a fluorescent probe based on a terbium-based metal–organic framework for selective detection of Fe(iii) and Al(iii)

“…Due to the energy mismatch between the ligand and Al 3+ , the increase of π* → π energy transfer of the ligand led to the enhanced fluorescence. 47–49 Several previous studies also reported similar phenomena and results. 50,51…”

Tuning the fluorescence sensing for Fe3+ ions by using different dipyridyl linkers in pillar-layered metal–organic frameworks

“…15 Many fluorescent MOFs were used to detect Fe 3+ ions by fluorescence quenching due to their many advantages including ease of use, quick detection ability, high sensitivity, highly selective response, diverse pore topologies, high surface area, and easy separation. 16–28…”

Self-assembled nanovesicles based on chiral bis-H8-BINOL for Fe3+ recognition and secondary recognition of l-cysteine by 1 + 1 complex

“…Due to the importance of transition metal ions in biology and the environment, the design and synthesis of uorescent sensors that can effectively recognize transition metal ions has attracted great interest. [6][7][8][9][10] The pollution by metal ions is increasing today with the rapid development of modern industry, especially industrial effluents discharged into rivers and lakes, etc. The pollution caused by transition metal ions pollution is the most serious, of which Fe 3+ pollution is the most common.…”
