“…[ 4,5 ] The arrangement processes of many materials play a vital role in tailoring several properties by changing the shape, dimension, aggregation, or composition. [ 6–9 ] It can achieve the various structural dimensions in the material utilizing coordination chemistry. The metal ions are linked with multimodal ligands to build secondary building units.…”

The naturally available cyclodextrin has opened up a wide range of research avenues because of its superior characteristics such as being non‐toxic, biocompatible, and edible. The cyclodextrin is the green multifunctional material that can add to the triboelectric series and extend its self‐powered applications. The ultrasonic synthesized cyclodextrin metal–organic framework (CD‐MOF) designed using sodium as a metal ion and cyclodextrin as a ligand for the triboelectric nanogenerator is reported. The various detailed characterizations of the CD‐MOFs give an insight into the properties of the synthesized material. The Kelvin probe force microscopy suggests three types of CD‐MOFs, exhibiting a positive potential. As per the surface potential, the output of the various CD‐MOF based TENG is varied as alpha CD MOF/Teflon > gamma CD‐MOF/Teflon > beta CD‐MOF/Teflon. The alpha CD MOF/Teflon TENG produces an electrical output of 152 V, 1.2 μA, and 14.3 nC, respectively. The fabricated device output is utilized for powering numerous low‐power electronics through a capacitor and bridge rectifier circuit. The multiunit Z‐shaped TENG device is attached to various surfaces such as the shoe heel and the backside of the school bag, and the corresponding energy harvesting response is demonstrated.

“…The entropy (Δ S ) of 7.62±1.16 J mol −1 K −1 is also quite small, indicating that the aggregation is possibly dimeric or oligomeric. The stability of aggregates is the result of a fine balance between the positive contribution of van der Waals interactions and the negative that derives from conformational factors and entanglement of side chains …”

Ap olyethylene-glycol-functionalized perylene bisimide (PEPBI) was synthesized. Its concentration-, solventand temperature-dependent visible spectra were measured and its aggregation states were analyzed. PEPBI exists as an aggregate dimer in aqueous solution or predominantly as a monomer in organic solvents. The anionic surfactant sodium dodecylbenzenesulfonate (SDBS) can disperse PEPBI as a monomer in aqueous solution.T he fluorescenceo ft hese solutions dependso nt he concentration of PEPBI and SDBS.The reduction of aggregated PEPBI with Na 2 Si ss low and the monoanion radical as well as dianion speciesa re the main forms of monomer.P EPBI exists predominantly as monomers in DMF andr eacts with Na 2 Sm uch faster.I nterestingly, the anionic radical species exist in H-aggregate form at low PEPBI concentrationsa nd J-aggregation occurs at high concentration. The dianion species is EPR-silent and its color highly depends on its concentration in DMF.

“…In general, multi-charged ILs have been shown to have a greater range of physical properties than their monocationic counterparts, such as higher density, glass transition, melting point, surface tension, and shear viscosity [25]. Like traditional ILs, they can be task-specific ionic liquids depending on their chemical structures [26], [27], [28], [29], [30], [31], [32], [33], [34]. Notable recent examples include tetracationic acidic organic salt based on 1,4-diazabicyclo [2], [2], [2]octane (DABCO) that are used as catalyst in the Knoevenagel condensation reactions in water [29], [30].…”
