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

open access: yesBeilstein Journal of Organic Chemistry
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
