2D Cd-MOF and its mixed-matrix membranes for luminescence sensing antibiotics in various aqueous systems and visible fingerprint identifying

Eu3+/Tb3+-modified Cd(ii) coordination polymers for effective detection of uric acid and lung cancer biomarker N-acetylneuraminic acid

“…As we all know, when the absorption band of the measured object overlaps with the excitation spectrum or emission spectrum of the sensor to a certain extent, the former may absorb energy and cause luminescence quenching, which is called the internal filtering effect (IFE). 53,54 Finally, considering the structural characteristic of the complex and UA, hydrogen interactions (O−H⋯O) may be formed between hydroxyl groups and UA within the crystal frameworks, giving rise to higher recognition. This was reflected by the X-ray photoelectron spectroscopy (XPS) results with the observation of slight O 1s or N 1s peak shifts: for O 1s, the displacement from 531.2 eV and 532.5 eV before soaking UA to 530.8 eV and 532.8 eV after soaking UA and for N 1s, the displacement from 399.1 eV and 404.7 eV before soaking UA to 399.0 eV and 404.9 eV after soaking UA (Fig.…”

Two isostructural Zn/Co-MOFs with penetrating structures: multifunctional properties of both luminescence sensing and conversion of CO2 into cyclic carbonates

“…36,37 We have been committed to the fabrication of MOFs with novel fluorescence sensing ability and/or catalytic functions. [38][39][40][41][42][43][44][45][46][47][48] In this work, two isostructural penetrating Zn/Co-MOFs, namely {[Zn(HL)(bpea)]•DMF} n (Zn-MOF-1) and {[Co(HL)(bpea)]•DMF} n (Co-MOF-2), were assembled from an ether-containing carboxylic acid of 3-(3,5-dicarboxybenzyloxy)benzoic acid (H 3 L). Both MOFs had multifunctional fluorescence sensing and catalytic properties.…”

Cd-MOF and Its Ln3+-Post Modification Products: Regulation of Luminescence Properties and Improved Detection of Uric Acid, Quinine, and Quinidine

“…Our group also have been engaged in constructing novel MOFs/CPs with luminescence sensing based on rigid aromatic carboxylates and flexible ligands with −CH 2 –O–, −CH 2 –NH–, or −NH–CO– bonds. − One recent work has carried out research to improve the sensing performance of Co-MOF ( LCU-112 ) and proved that it can detect and distinguish Al 3+ and Pb 2+ in the presence of Tb 3+ more effectively . Furthermore, visualization of quenching effect toward Fe 3+ could also be improved by replacing LCU-112 with Tb 3+ postsynthesized sample Tb 3+ @LCU-112 .…”
