“…The high-resolution Al 2p XPS spectrum exhibited the peak at 75.28 eV, illustrating the successful loading of the Al 3+ ion (Figure S57). Importantly, in 1 (Figure S3), the high-resolution XPS spectrum of N 1s of the nitrogen atom of the −NH peak appeared at 400.43 eV, and the XPS peak for the same atom is displayed at 400.22 eV upon the introduction of the Al(NO 3 ) 3 ion with 1 , i.e., in Al(NO 3 ) 3 @ 1 (Figure S57). This clearly validates the possible interaction between the Al 3+ ion and N of the −NH functionality of the linker of the framework.…”

The exploration of smart sensors is of great significance for the selectivity, sensitivity, and ability to show the low detection limit for the target analyte. Here, we have used the linker H 2 L (5-((anthracen-9-ylmethyl)amino)isophthalic acid) for the construction of {[Cd(L)(DMF)(H 2 O) 2 ]•H 2 O} n (1) which is in order with the chromophore anthracene moiety and the free −NH functionality as a guest interaction site. This framework showed the luminescence recovery "turn-on" detection of the Al 3+ ion in an aqueous solution. An exhaustive mechanism study disclosed that the Lewis acid−base-type interaction between the Al 3+ ion and the −NH functionality of the linker in the framework revealed that the absorbance caused an enhancement for the "turn-on" sensing event. Besides the "turn-on" sensing event, the "turn-off" sensing phenomenon of 1 is also noticed when it detects the hazardous oxo-anions (MnO 4 − and CrO 4 2−) with limit of detection values of 17.08 and 19.91 ppb, respectively. The detection of these diverse analytes are very fast (10 s) and they can also be recognized through a colorimetric response. The sensing mechanisms for these analytes are established by photoinduced electron transfer, Forster resonance energy transfer, and inert filter effect along with theoretical investigation. Furthermore, to show the sensing application of 1 in a versatile podium, a MOF gel composite, 1@AA (AA = Agar−Agar), was developed from 1 with AA. Interestingly, 1@AA showed the colorimetric detection of these analytes under UV light. Therefore, sensor 1 behaves as a smart sensory material for the recognition of the above analytes through a simultaneous "turnon" and "turn-off" effect.

“…For less conductive MOFs, usually supported by multi‐dentate carboxylic acid or imidazole organic linkers, it is a traditional way to prepare MOF hybrids/composites to enhance conductivity so as to improve capacitance performances of supercapacitors. Conducting polymers constantly appeared in Co MOFs, [ 136,142,197 ] Zr MOFs, [ 170,198–200 ] and Zn MOFs [ 201,202 ] besides POM hybridized Cu MOFs [ 203 ] and Co MOFs, [ 204 ] COFs hybridized Zr MOFs, [ 205 ] rGO hybridized Al MOFs [ 206 ] and Cu MOFs, [ 207,208 ] carbon nanofibers hybridized Ni MOFs, [ 209 ] CNTs hybridized Ni MOFs, [ 210 ] and sulfur‐doped graphene bimetallic CuFe MOFs.

The preparation of electroactive metal–organic frameworks (MOFs) for applications of supercapacitors and batteries has received much attention and remarkable progress during the past few years. MOF‐based materials including pristine MOFs, hybrid MOFs or MOF composites, and MOF derivatives are well designed by a combination of organic linkers (e.g., carboxylic acids, conjugated aromatic phenols/thiols, conjugated aromatic amines, and N‐heterocyclic donors) and metal salts to construct predictable structures with appropriate properties. This review will focus on construction strategies of pristine MOFs and hybrid MOFs as anodes, cathodes, separators, and electrolytes in supercapacitors and batteries. Descriptions and discussions follow categories of electrochemical double‐layer capacitors (EDLCs), pseudocapacitors (PSCs), and hybrid supercapacitors (HSCs) for supercapacitors. In contrast, Li‐ion batteries (LIBs), Lithium‐sulfur batteries (LSBs), Lithium‐oxygen batteries (LOBs), Sodium‐ion batteries (SIBs), Sodium‐sulfur batteries (SSBs), Zinc‐ion batteries (ZIBs), Zinc–air batteries (ZABs), Aluminum‐sulfur batteries (ASBs), and others (e.g., LiSe, NiZn, H+, alkaline, organic, and redox flow batteries) are categorized for batteries.

“…Majumder et al prepared an aluminum-based MOF, MIL-53(Al), and reduced graphene oxide (rGO) composite, abbreviated as MIL-53(Al)@rGO, for supercapacitor application. 163 A two-step solvothermal technique was used to synthesize MIL-53(Al)@rGO. 1 M KOH solution was used as an electrolyte for the measurement of electrochemical experiments of C-1 (MIL-53 (Al)), C-100 (rGO), and MIL-53(Al)@rGO) hybrid composites (C-2 to C-50) in a three-electrode system.…”
