Facile access to pyridinium-based bent aromatic amphiphiles: nonionic surface modification of nanocarbons in water.

ABSTRACT: Efficient water-solubilization of nanocarbons is desirable for both their biological and material applications, but so far has mainly relied on covalent modifications or amphiphiles featuring ionic side-chains. Here, we report a facile 2-4-step synthesis of pyridinium-based, bent aromatic amphiphiles with modular nonionic side-chains (i.e., CH₃ and CH₂CH₂(OCH₂CH₂)₂-Y (Y = OCH₃, OH, and imidazole)). The new amphiphiles quantitatively self-assemble into ≈2 nm-sized aromatic micelles in water independent of the side-chain. Importantly, efficient water-solubilization and nonionic surface modification of various nanocarbons (e.g., fullerene C₆₀, carbon nanotubes, and graphene nanoplatelets) are
