Self-assembly in morphological organization of various fullerene derivatives affords different supramolecular architectures. Nanospheres, tubules, and bundles of nanorods are formed depending on the nature of the organic group in the fullerene unit. The current work highlights an efficient method to fabricate almost perfect and uniformly shaped nanocrystals in a novel connection between spherical fullerene-based materials and fibrous nanotubes. In a parallel research line, carbon nanotubes (CNTs) have been functionalized using 1,3-dipolar cycloaddition of azomethine ylides. The organically functionalized CNTs, having improved solubility and potential for applications, are characterized by standard analytical methods as well as microscopy techniques.

Hybrid Carbon

This report deals with a simple and efficient method to develop hybrid carbon nanoparticles (Nps) employing Multi-walled carbon nanotubes (MWCNTs) and Fullerene nps. Fullerene nps were self-assembled via Ultrasonicated Liquid-Liquid Precipitation. Surface treated MWCNTs were entangled with fullerene nps during the process of assembling of the fullerene nps. Fullerene nps are formed by reaction between two solutions, one is the saturated solution which contains dissolved fullerene and other solution is a rough alcohol. This reaction increases the concentration of carbon in the solution and leads to super saturate hence self-assembling into nanoparticles. The obtained hybrid nanoparticles sizes were in the range of 100 nm to 300 nm with entangled mwcnts and were confirmed by characterization using SEM, Raman, UV-Vis, XRD, and DLS.

A general approach to substituted pyrrolidines via [3 + 2] 1,3-dipolar cycloaddition between nonstabilized azomethine ylides and cyanosulfones was developed. The efficient method provides a series of substituted pyrrolidines bearing a quaternary carbon center in high yields (up to 98%) excellent diastereoselectivities (up to >25:1 dr) under ambient reaction conditions.
