• (CNTs) by growing dendrimers on their surface. First, CNTs were pre-functionalized with maleic acid (MA) via Diels–Alder reaction in presence of a deep eutectic solvent under ultrasonication. Subsequently, dendrimers of varying length were grown by the repeated reaction of ethylene diamine and MA. Raman

• spectroscopy was specifically used to confirm the Diels–Alder reaction on the surface of CNTs, and other characterization techniques (SEM, EDX, XRD, TGA, and FTIR) were applied to confirm the successive growth of the dendrimers. Highly dendrimerized CNTs were found to be more effective in removing heavy metal

• involvement of harmful chemicals to pre-functionalize the CNTs with high loading but also provided an effective way to enhance the adsorption of heavy metal ions.

• ]. The different reactions for functionalization include cycloadditions such as the Diels–Alder reaction and the addition of azomethine ylides, carbene and nitrene addition, chlorination, bromination and hydrogenation [40]. Different chemically attached functional groups on the sidewalls of nanotubes are

• group of Wang [56] explored a different strategy to integrate a substituted naphthylene unit into CPP (Scheme 8). The square shaped subtituent was synthesized via Diels–Alder reaction of 35 and 31 selectively affording the cis product 36 after methylation. This building block was further submitted to
