“…The order of LUMO energy is PCL ˃ SDZ ˃ CAP ˃ DTZ ˃ NFT, which is in accordance with the quenching efficiency ( Supplemental Figure S5 and Table S3 ). The results indicate that the photo-induced electron transfer (PET) process is pivotal in detecting antibiotics [ 37 , 38 , 39 , 40 ]. Thus, the fluorescence quenching of complex 1 toward UO 2 2+ , Cr 2 O 7 2− /CrO 4 2− and NFT is caused by the competitive absorption and PET mechanism.…”

A new Ni coordination polymer [Ni(MIP)(BMIOPE)]n (1) was constructed (BMIOPE = 4,4′-bis(2-methylimidazol-1-yl)diphenyl ether, and H2MIP = 5-methylisophthalic acid), possessing two-dimensional (2D) twofold parallel interwoven net structure with a 44∙62 point symbol. Complex 1 has been successfully obtained based on mixed-ligand strategy. The fluorescence titration experiments revealed that complex 1 could act as multifunctional luminescent sensor to simultaneously detect UO22+, Cr2O72− and CrO42−, and NFT (nitrofurantoin). The limit of detection (LOD) values for complex 1 are 2.86 × 10−5, 4.09 × 10−5, 3.79 × 10−5 and 9.32 × 10−5 M for UO22+, Cr2O72−, CrO42− and NFT. The Ksv values are 6.18 × 103, 1.44 × 104, 1.27 × 104 and 1.51 × 104 M−1 for NFT, CrO42−, Cr2O72− and UO22+. Finally, the mechanism of its luminescence sensing is studied in detail. These results manifest that complex 1 is a multifunctional sensor for sensitive fluorescent UO22+, Cr2O72−, CrO42− and NFT detection.

“…It is essential for electron transport, catalysis, and biological activities. Conversely, the excessive intake can significantly impact human health, and improper discharge can lead to environmental pollution. − The detection of Fe 3+ has been achieved through diverse analytical techniques such as voltammetry, chromatography, inductively coupled plasma (ICP) mass spectroscopy, atomic absorption spectroscopy, etc. , However, they are not user-friendly because of their high cost and complex instrument operation. Furthermore, their sensing sensitivity and selectivity are challenged in the complicated water environment. , Thus, it is necessary to develop a convenient and high-performance method for sensing Fe 3+ in H 2 O.…”

The design and synthesis of high-performance sensors are very important but remain great challenges. In this work, a new aggregation-induced-emission (AIE) molecule 4,4′-(((9H-fluoren-9-ylidene)methylene)bis(4,1-phenylene))dipyridine (L) was successfully synthesized and first developed as a functional ligand to construct two isomorphic metal−organic frameworks (MOFs) [M(L)(OBBA)] n [M 2+ = Cd 2+ (1), Co 2+ (2); H 2 OBBA = 4,4′-oxybisbenzoic acid]. They adopt [M 2 (COO) 4 ] flywheel clusters, OBBA 2− bridges, and terminal L ligands as building units to form isomorphic 2-D networks with Lewis base active cites (uncoordinated pyridyl N). Both 1 and 2 exhibit excellent water, pH, and thermal stabilities and extremely efficient Fe 3+ sensing abilities in the water environment. The quenching constants and detection limits reach the best levels reported so far. The sensing mechanism of 1 and 2 toward Fe 3+ is studied in depth, and the difference in their sensing performance is also explained.
