A viologen-functionalized europium-based metal–organic framework, denoted as compound 1, has been synthesized solvothermally by employing 1,1′-bis(3,5-dicarboxyphenyl)-4,4′-bipyridinium dichloride (abbreviated as H4bdcbpCl2). Compound 1 possesses a 2-fold parallel self-interpenetrating structure composed of two sets of identical three-dimensional (3D) cationic frameworks with {4·84·12}2{42·82·102}{8}2 topology. The introduction of tetracarboxylic group-decorated viologen derivative not only facilitates the formation of a helix-based structure with high dimensionality and positively charged framework but also promotes the photoinduced electron transfer (PET)-caused photochromic property. Significantly, compound 1 demonstrates a rapid detection process for nitrofurantoin (NFT) and nitrofurazone (NFZ) in aqueous environments, exhibiting good recycling stability, large quenching coefficient (K sv), low limit of detection (LOD), and high anti-interference ability through a fluorescence turn-off mechanism. This phenomenon was further investigated through spectroscopic analyses and density functional theory (DFT) calculations. Moreover, compound 1 also exhibits sensing capabilities for various ions in aqueous system, including Fe3+, Cr2O7 2–, and MnO4 –, which further verify that compound 1 could serve as a multifunctional fluorescence sensor for molecular and ionic pollutants.

“…4 ). By comparing the XRD patterns of Fe 3 O 4 and Fe 3 O 4 @SiO 2 @TAD-G2-SO 3 H, it can be confirmed that the ferrite core remains stable without undergoing any phase changes during the functionalization process 52 . The XRD patterns of the prepared Fe 3 O 4 @SiO 2 @TAD-G2-SO 3 H show distinct diffraction peaks at 2 θ = 30.2°, 35.4°, 43.7°, 56.6°, and 63.0°, corresponding to the (220), (311), (400), (422), (511), and (440) Miller planes of Fe 3 O 4 nanoparticles.…”

A novel solid acid catalyst with recoverability, named as Fe3O4@SiO2@TAD-G2-SO3H, was successfully synthesized by immobilizing sulfonic acid groups on triazine dendrimer-modified magnetic nanoparticles. This nanomaterial structure and composition were thoroughly characterized using various analytical techniques, including thermogravimetric analysis (TGA), elemental analysis, Fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX), elemental mapping, acid–base titration, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and vibrating sample magnetometry (VSM). The acid-decorated magnetic dendrimer was served as a highly effective catalyst for the synthesis of tetrahydrobenzo[c]acridin-8(9H)-one and benzo[h]indeno[1,2-b]quinoline-8-one derivatives. The reaction proceeded smoothly under mild conditions through the one-pot condensation of aromatic aldehydes, 1-naphthylamine, and either dimedone or 1,3-indanedione, affording the desired products in high yields ranging from 90 to 96%. The catalyst was easily separated from the reaction mixture by employing a magnetic field, allowing for its recycling up to five times with slight loss in its activity (only 10%). Nearly, quantitative recovery of catalyst (up to 95%) could be obtained from each run. So, this catalyst facilitates the reaction progress and simplifies the purification process. Other remarkable features of this method are operational simplicity, excellent yields, mild condition, and a wide range of substrate applicability.
