title: Corannulene Molecular Rotor with Flexible Perfluorobenzyl Blades: Synthesis, Structure and Properties.
abstract: Two members of a new class of organic-acceptor perfluorobenzyl corannulenes were prepared by gas-phase and highly-selective solution-phase reactions at elevated temperatures. The peculiar single-crystal X-ray structure of C5-C20H5(CF2C6F5)5 revealed two high-energy conformers with drastically different bowl depths and orientations of perfluorobenzyl blades; the conformers are alternating in columnar packing arrangements and every pair is sandwiched by toluene molecules.
