Highly water-stable Cd-MOF/Tb3+ ultrathin fluorescence nanosheets for ultrasensitive and selective detection of Cefixime

Four Novel Lanthanide(III) Metal–Organic Frameworks: Tunable Light Emission and Multiresponsive Luminescence Sensors for Vitamin B6 and Pesticides

“…It further suggests that 2 and VB 6 have a weak interaction. Nevertheless, the excitation spectrum of complex 2 has a major overlap with the ultraviolet spectrum of VB 6 (Figure S12b), which suggests that an inner filter effect exists (IFE) between complex 2 and VB 6 . The excitation energy of complex 2 is partly absorbed by VB 6 , which leads to fluorescence quenching of 2 .…”

“…The UV–vis spectrum of DCN has the largest overlap with the excitation spectrum of 2 , which indicates that there is an IFE between DCN and complex 2 (Figure S14). , The excitation energy of complex 2 can be partly absorbed by DCN, resulting in fluorescence quenching. Moreover, the XPS spectrum shows that the 3d peak of Tb­(III) in 2 has shifted from 1242.27 to 1242.26 eV after addition of DCN, which indicates a weak interaction between 2 and DCN (Figure S15).…”

Highly sensitive detection of nitrobenzene by a series of fluorescent 2D zinc(ii) metal–organic frameworks with a flexible triangular ligand

“…Thus, the electron may transfer from the framework to the NB under photo-induction, which is considered as the PET effect causing the fluorescence quenching of NB. 20 …”

High‐efficiency fluorescent probe constructed by Cd(II) complex for detecting nitro compounds and antibiotics

“…Common fluorescence quenching can be attributed to framework collapse, fluorescence resonance transfer (FRET), [91][92][93][94] and inner filter effect (IFE). [95][96][97][98] As shown in Figure S12, after cycle test, the PXRD spectra of the complex have the same diffraction peak as before, indicating that the framework structure of the complex has not changed and the fluorescence quenching caused by the collapse of the framework can be ruled out. At the same time, this experiment studied the UV-vis absorption spectra of p-nitrophenol and nitroimidazole antibiotics.…”
