One cadmium (II)-based metal−organic framework as high-efficiency multi-functional fluorescence chemosensor targeting for the determination of Fe3+, Cr2O72– and CrO42– in aqueous phase

Designing a Polyoxometalate-Incorporated Metal–Organic Framework for Reduction of Nitroarenes to Anilines by Sequential Proton-Coupled Electron Transfers

“…The life curve of CoW-TPT conforms to the double exponential function, τ 1 and τ 2 were 1.88 μs (50.82%) and 9.30 μs (49.18%), respectively, and the agreement factor (χ 2 ) was 1.142. The luminescence lifetime of CoW-TPT was around 5.53 μs by calculation (Figure c) . This indicates that CoW-TPT produces stable excited intermediates under light conditions, which provides the possibility for the photocatalytic reduction of NB.…”

“…The luminescence lifetime of CoW-TPT was around 5.53 μs by calculation (Figure 3c). 38 This indicates that CoW-TPT produces stable excited intermediates under light conditions, which provides the possibility for the photocatalytic reduction of NB. It was further demonstrated that there was a sequential photoinduced charge-transfer (PET) process among the components of CoW-TPT through the coordination bonds and π•••π interactions during irradiation.…”

Fabrication of 5-R-isophthalic acid-modulated cadmium–organic coordination polymers and selectivity for the efficient detection of multiple analytes

“…Usually, they show an excellent fluorescence effect and can be used for rapid and effective detection of some pollutants. 17,18 For example, Yang and colleagues reported a three-dimensional (3D) Cd-CP using mixed ligands with conjugated systems having symmetric carboxyl groups on the benzene ring which displayed chemical-sensing behavior for Fe 3+ , Cr 2 O 7 2− , and CrO 4 2− . 17 Using solvothermal synthesis, Lv and colleagues synthesized a Cd-CP that possessed excellent water stability and was used for the detection of Fe( iii ) and Al( iii ) simultaneously with high selectivity and sensitivity.…”

A series of bis-pyridyl-bis-amide-modulated metal–organic frameworks: formation, transformation and selectivity for the efficient detection of multiple analytes

“…12,13 For example, Yang and co-workers had reported a Cd-based LMOF, which behaved as a multi-functional chemosensor toward Fe 3+ , Cr 2 O 7 2− and CrO 4 2− . 14 Gao et al had prepared a bifunctional 3D porous Zn-based LMOF, which can sensitively recognize Fe 3+ ions in an aqueous medium. 15 However, there have been few reports on the systematic study of the effects of organic ligands on the luminescence sensing properties of Zn/Cd-based LMOFs until now.…”
