Pressure-induced polymerization (PIP) of aromatics is a novel method to construct sp3-carbon frameworks, and nanothreads with diamond-like structures were synthesized by compressing benzene and its derivatives. Here, by compressing benzene-hexafluorobenzene cocrystal (CHCF), we identified H-F-substituted graphane with a layered structure in the PIP product. Based on the crystal structure determined from the in situ neutron diffraction and the intermediate products identified by the gas chromatography-mass spectrum, we found that at 20 GPa CHCF forms tilted columns with benzene and hexafluorobenzene stacked alternatively, which leads to a [4+2] polymer, and then transfers to short-range ordered hydrogenated-fluorinated graphane. The reaction process contains [4+2] Diels-Alder, retro-Diels-Alder, and 1-1' coupling, and the former is the key reaction in the PIP. In conclusion, our studies confirmed the elemental reactions of the CHCF for the first time, which provides a novel insight into the PIP of aromatics.
