These COFs were successfully compared with their solvothermally synthesized counterparts in all aspects. These solvent-free mechanochemically synthesized COFs have moderate crystallinity with remarkable stability in boiling water, acid (9 N HCl), and base [TpBD (MC) in 3 N NaOH and TpPa-2 (MC) in 9 N NaOH]. Exfoliation of COF layers was simultaneously observed with COF formation during mechanochemical synthesis. The structures thus obtained seemed to have a graphene-like layered morphology (exfoliated layers), unlike the parent COFs synthesized solvothermally.</p>1 aBiswal, Bishnu, P.1 aChandra, Suman1 aKandambeth, Sharath1 aLukose, Binit1 aHeine, Thomas1 aBanerjeet, Rahul  uhttps://library.ncl.res.in/content/mechanochemical-synthesis-chemically-stable-isoreticular-covalent-organic-frameworks-0
