The first water-soluble C 3v -symmetrical trannulene derivatives of fluorofullerene C 60 F 18 possessing six carboxylic or ammonium ion groups have been synthesized and spectrally characterized. The stability of emerald-green aqueous solutions of these compounds was investigated. A novel synthetic route was developed for a step-by-step derivatization of C 60 F 18 with different organic C-H acids that yielded nonsymmetrically substituted C 60 F 15 R 2 RЈ trannulenes. The synthesized trannulenes were loaded with polar carboxylic groups that improved greatly the solubility of these compounds in aqueous media. We showed that four solubilizing COOH
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
