One of the critical issues for the application of single-wall carbon nanotubes (SWCNTs) in nanoelectronics is the control of their electronic properties, which can be either metallic or semiconducting in their pristine form, depending on their diameter and chirality. Since all known preparative methods yield mixtures of metallic and semiconducting nanotubes, extensive research has been devoted ...
Abstract A new multi-site phase-transfer catalyst (MPTC), viz., N,N’-dioctyl-4,4’-bipyridium dibromide containing bi-site was prepared and proved by FT-IR, 1H NMR, 13C NMR, mass and elemental analysis. The enhancement of C-N+ peak intensity at 1179 cm−1 noticed in FT-IR, the agreement of m/z values, viz., 542.43 bi-site respectively with their theoretical values and the percentage of C, H, N e...
C functionalization of graphene significantly broadens its application potential via tuning its electronic and surface properties. Therefore, a wide range of dry and wet chemistry approaches have been developed for graphene functionalization. Despite recent progress in this field, covalent modification of graphene is still hampered by its low reactivity. Moreover, the reactivity depends on the ...
