Trifluoromethyl/Perfluoroalkyl Corannulenes: Directed Synthesis and Photophysical Characterization

Abstract

Copper-mediated methods for the synthesis of perfluoroalkyl-substituted corannulene derivatives have been developed, including long-chain derivatives such as perfluorooctyl. The moderate to high yields of these mild and selective methods enable the production of sufficient amounts of material to conduct extensive electrochemical and photophysical measurements on a cognate series of compounds. The electrochemical measurements reproduce well previous measurements. The optical measurements display a constant set of electronic transitions across the series.
