“…18,35,36 Moreover, the lipophilic properties of the nano-lanthanum complex are enhanced due to the delocalization of p electrons in the aromatic ring, and according to the chelation theory, the polarity of the metal ion decreases. 37,38 In addition, due to the decrease in the polarity, the probability of chelating with the ligand (MFA) is increased and the interactions of the nano-lanthanum complex with MFA are normally due to covalent and ionic bonding.

“…Lastly, the strong electronegativity of the fluoride ion made a photoinduced electron transfer within the Co-MOF structure, leading to a photoluminescence red shift. 66 − 68 The resulting exclusive host–guest interactions (Lewis acid–base interactions) between the host site (Co-MOF) and the guest site (F – ) induced a fast photoluminescence behavior with the Co-MOF, and finally, a highly sensitive, selective, and applicable fluoride ion chemosensor was developed.…”

The development of selective and fast optical sensitive chemosensors for the detection and recognition of different cations and anions in a domain is still a challenge in biological, industrial, and environmental fields. Herein, we report a novel approach for the detection and determination of fluoride ion (F – ) sensing based on a salen-cobalt metal-organic framework (Co(II)-MOF). By a simple method, the Co(II)-MOF was synthesized and characterized using several tools to elucidate the structure and morphology. The photoluminescence (PL) spectrum of the Co(II)-MOF (100.0 nM/L) was examined versus different ionic species like F – , Br – , Cl – , I – , SO 4 2– , and NO 3 – and some cationic species like Mg 2+ , Ca 2+ , Na + , and K + . In the case of F – ions, the PL intensity of the Co(II)-MOF was scientifically enhanced with a remarkable red shift. With the increase of F – concentration, the Co(II)-MOF PL emission spectrum was also professionally enhanced. The limit of detection (LOD) for the Co(II)-MOF chemosensor was 0.24 μg/L, while the limit of quantification (LOQ) was 0.72 μg/L. Moreover, a comparison of the Co(II)-MOF optical approach with other published reports was studied, and the mechanism of interaction was also investigated. Additionally, the applicability of the current Co(II)-MOF approach in different real water samples, such as tap water, drinking water, Nile River water, and wastewater, was extended. This easy-to-use future sensor provides reliable detection of F – in everyday applications for nonexpert users, especially in remote rural areas.

“…Upon excitation at 381 nm the emission of the framework near 450 nm was quenched, while the emission of the dyes (530 nm for C6 and 510 nm for C343) was enhanced, indicating energy transfer from the network to the dyes molecules [207]. Wu [208]. It exhibited an intraligand emission peak at 410 nm upon excitation at 300 nm.…”

Coordination Polymers Based on Highly Emissive Ligands: Synthesis and Functional Properties

et al. 2020

Coordination polymers are constructed from metal ions and bridging ligands, linking them into solid-state structures extending in one (1D), two (2D) or three dimensions (3D). Two- and three-dimensional coordination polymers with potential voids are often referred to as metal-organic frameworks (MOFs) or porous coordination polymers. Luminescence is an important property of coordination polymers, often playing a key role in their applications. Photophysical properties of the coordination polymers can be associated with intraligand, metal-centered, guest-centered, metal-to-ligand and ligand-to-metal electron transitions. In recent years, a rapid growth of publications devoted to luminescent or fluorescent coordination polymers can be observed. In this review the use of fluorescent ligands, namely, 4,4′-stilbenedicarboxylic acid, 1,3,4-oxadiazole, thiazole, 2,1,3-benzothiadiazole, terpyridine and carbazole derivatives, naphthalene diimides, 4,4′,4′′-nitrilotribenzoic acid, ruthenium(II) and iridium(III) complexes, boron-dipyrromethene (BODIPY) derivatives, porphyrins, for the construction of coordination polymers are surveyed. Applications of such coordination polymers based on their photophysical properties will be discussed. The review covers the literature published before April 2020.
