“…Very recently, some of us have reported the first example of a COF material grafted with lanthanides, where we show the possibility to obtain white‐light emission . Soon afterwards, several reports on lanthanide COFs have followed, showing the large interest in this research field . Also, it is worth mentioning that white light can be obtained just from a COF itself, and several luminescent materials like this have already been reported …”

Covalent Organic Frameworks (COFs), an emerging class of crystalline porous materials,are proposed as anew type of support for grafting lanthanide ions (Ln 3+ )a nd employing these hybrid materials as ratiometric luminescent thermometers.ATpBpy-COF-prepared from 1,3,5-triformylphloroglucinol (Tp) and 2,2'-bipyridine-5,5'-diamine (Bpy) grafted with Eu/Tb and Dy acetylacetone (acac) complexes can be successfully used as al uminescent thermometer in the 10-360 K( Eu) and 280-440 K( Tb) ranges with good sensing properties (thermal sensitivity up to 1.403 %K À1 ,t emperature uncertainty dT < 1Kabove110 K). Forthe Eu/Tb systems,we observe an unusual and rarely reported behavior,t hat is,n o thermal quenching of the Tb 3+ emission, aresult of the absence of ion-to-ligand/host energy back-transfer.T he LnCOF materials proposed here could be anew class of materials employed for temperature-sensing applications following up on the wellknownluminescent metal-organic framework thermometers.

“…successfully grafted a complex of europium (Eu) IL and 2‐thenoyltrifluoroacetone (TTA) on DhaTab‐COF by stepwise post‐synthetic method ( Figure a). [ 34 ] First, 2,5‐dihydroxyterephthalaldehyde (Dha) and 1,3,5‐tris(4‐aminophenyl)benzene (Tab) were used as precursors to prepare DhaTab‐COF through Schiff base reaction and then DhaTab‐COF‐IL was obtained via Williamson ether reaction between phenol group in DhaTab‐COF and (2‐bromoethyl)triethylammonium bromide ([BrEt 4 N]Br); subsequently, the Eu‐based IL complex (Eu(TTA) 4 [BrEt 4 N]) was grafted on DhaTab‐COF by ion displacement. The PXRD patterns of DhaTab‐COF‐IL and DhaTab‐COF‐EuIL exhibited their identical (100), (110), (200), (120), and (220) facets, indicating the crystal integrity.…”

“…synthesized a DhaTab‐COF‐EuIL composites with remarkable fluorescence quenching effect toward acetone (Figure 6b). [ 34 ] Because of extended π‐conjugation and luminescent Eu‐based complex with three luminescence emissions at 592, 614, and 650 nm corresponding to 5D 0 →7F J ( J = 0–3) transitions of Eu 3+ , the DhaTab‐COF‐EuIL exhibited excellent luminescence properties which was studied by dispersing it into DMF. The visual exhibition was perceived that the luminescence of DhaTab‐COF‐EuIL disappeared concomitantly with the increasing of acetone in the mixtures of acetone and DMF, indicating the high fluorescence quenching of DhaTab‐COF‐EuIL to acetone.…”

The functional composites based on covalent organic frameworks (COFs) and ionic liquids (ILs) have stimulated increasing scientific interest owing to their complementary characteristics and cooperative activation. The tailorability and diversity of COFs and ILs render the COFs‐ILs composites with predesignable structures, extendable syntheses, and customizable functionalities. Although the COFs‐ILs composites have a promising development prospect, thus far, reviews regarding COFs‐ILs composites have not been reported. This minireview summarizes the synthetic strategies including ionothermal synthesis and solvothermal synthesis; in addition, the application performances of meritorious COFs‐ILs composites ranging from catalysis, electrochemistry, adsorption and separation, luminescence sensing, and bio‐related analysis are briefly introduced. Furthermore, this minireview briefly emphasizes the opportunities and challenges faced toward rapidly developed but embryonic COFs‐ILs composites. Altogether, it is expected that this minireview will spark the potential development of COFs‐ILs composites from fundamental synthesis to cutting‐edge applications.

“…Recently, Zho and coworkers reported an Eu(III)‐MOF with imine nitrogen and OH functionalities that showed electrostatic interactions with acetone molecules, resulting in quenching of the luminescence spectra of the MOF. [ 198 ] Furthermore, intermolecular interactions were observed between a Cu(II)‐MOF sensor and acetone. These interactions resulted in a specific luminescent MOF sensor for acetone, with a LOD of ≈20 ppm.…”

The success of MOFs has driven their development as a new tool for sensing analytes including toxic chemicals. [19][20][21] The MOF sensors can be applied in both environmental and biological systems. [22] The MOF sensor field has been established with the development of sensors for different metal ions, anions, and molecules. [23,24] The potential application of MOF sensors to the detection of heavy metal ions, toxic anions, and other hazardous species is of great interest. [25,26] Specifically, luminescence technology has allowed the roles of various MOF sites in analyte capture to be easily studied. [27][28][29] The precise use of MOFs is potentially a good tool for analyte detection. Furthermore, MOFs have been established as potential materials for selective, fast, and portable tools for sensing toxic chemicals, with the advantage of light-emitting properties. [30,31] Interestingly, these sensing models can operate in water and are pH stable with high efficiency. [32] Furthermore, MOFs are wellknown materials for the degradation of toxic chemicals. [33,34] Several reports have been published on MOF sensors for toxicant chemicals, such as metal ions, anions, organic solvents, pesticides, nitroaromatic compounds (NACs), chemical warfare agents, [35] and others. [36][37][38] Some reviews have summarized applications of MOFs in sensing and detection probes for ions and volatile organic compounds, [39] and MOF sensors in pesticide detection and absorption with their classification. [40] Others have summarized and analyzed interactions between hazardous compound adsorbates and MOFs. [41,42] The stability and applications of MOFs have been summarized by the research groups of Ding and coworkers. [43] Pehlivan and et al. summarized the role of fluorescence resonance energy transfer in elucidating molecular interactions utilized in biosensing tools. [44,45] Besides luminescence sensing, the reviewers summarized the progress of MOFs relevance in the various area including environment and medical science. [46] Recently, Liu and coworkers summarized the progress of MOFs and discussed the remaining challenges in drug delivery, [47] Garcia and coworkers studied and compared the MOFs as photocatalysts with common inorganic photocatalysts, [48] and Manos and coworkers studied and summarized MOFs challenges and prospects for ion-exchange and sorption applications. [49] Despite these meaningful reviews, the factors responsible for signal changes, mechanisms, and limits of detection have Mechanistic studies of materials able to detect hazardous and toxic chemicals, such as common organic solvents, pesticides, and nitroaromatic compounds (NACs), are critically important owing to the threat they pose to humans and the environment. Recently, porous luminescent metal-organic frameworks (MOFs) with multifunctional sites, high surface areas, and structural tunability have emerged as sensory devices for the detection of hazardous and toxic chemicals. Herein, recent progress regarding the mechanistic behavior of MOF sensors in the det...
