An unusual (3,10)-coordinated 3D network coordination polymer as a potential luminescent sensor for detection of nitroaromatics and ferric ion

A family of Cd(ii) coordination polymers constructed from 6-aminopicolinate and bipyridyl co-linkers: study of their growth in paper and photoluminescence sensing of Fe3+ and Zn2+ ions

“…66 The obtained values fall in the range of other CPs for the detection of Fe 3+ in aqueous media but in the top range of detectors among those performing sensing in water (see Table S28†). 40,67–69…”

Recent Advances in Nanocomposite Luminescent Metal-Organic Framework Sensors for Detecting Metal Ions

“…[165] A cadmium coordination polymer {[Cd 3 (itp) 2 (btc) 2 ]•4H 2 O} n , where itp is imidazol-1-yl-3-(1,2,4-triazol-4-yl) propane and btc is 1,3,5-benzenetricarboxylate), was synthesized and characterized. [166] The 3-D network based on the [Cd 3 (COO) 4 ] trimeric clusters showed a good luminescence sensor for detection of nitroaromatics as well as Fe 3+ , even in the presence of the competing ions. These selective luminescence quenching phenomena are attributed to the energy-transfer quenching mechanism that provides a 0.12 μM detection limit for the Fe 3+ ion.…”

“…Cd-based MOFs have been extensively used as luminescence sensors for Fe 3+ detection, as well as some small organic molecules. [142,[159][160][161][162][163][164][165][166][167][168][169][170][171][172][173][174][175][176] For example, self-assembly of Zn/Cd-coordination polymers based on 3,3′,4, 4′biphenyltetracarboxylic acid and N-donor ligands was prepared via a hydrothermal process in DMF solution (labeled as complex 2). [142] The Cd-based complex provides a 3-D network structure with fluorescence properties that displayed highly selective and sensitive sensing for Fe 3+ ions in DMF solution.…”

“…These selective luminescence quenching phenomena are attributed to the energy-transfer quenching mechanism that provides a 0.12 μM detection limit for the Fe 3+ ion. [166] Gao and coworkers have reported a highly sensitive and recyclable sensing of Fe 3+ ions based on a luminescent anionic [Cd(DMIPA)] 2framework with exposed thioether group. It showed ligand-based photoluminescence and solvent-dependent fluorescent intensities that are sensitive and selective toward Fe 3+ ions in the presence of various metal ions.…”
