Perfluorinated aromatic compounds, the so-called perfluoroarenes, are {widely|extensively|broadly} {used|utilized|employed|utilised|applied|made use of} in {materials|supplies|components} science owing to their {high|higher} electron affinity and characteristic intermolecular interactions. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, {methods|techniques|strategies|approaches|procedures|solutions} to synthesize {highly|extremely|very|hugely} strained perfluoroarenes have remained elusive so far, which {greatly|significantly|tremendously|drastically|considerably} limits their structural diversity. Herein, we report the synthesis and isolation of perfluorocycloparaphenylenes (PFCPPs) as a class of ring-shaped perfluoroarenes. {Using|Utilizing|Making use of|Employing|Working with|Applying} macrocyclic nickel complexes, we succeeded in synthesizing PF[n]CPPs (n = {10|ten}, 12, 14, 16) in one-pot {without|with out|without having|with no|devoid of|without the need of} noble metals. The molecular structures of PF[n]CPPs (n = {10|ten}, 12) {were|had been|have been} determined by X-ray crystallography to confirm their tubular alignment. Photophysical and electrochemical measurements revealed that PF[n]CPPs (n = {10|ten}, 12) exhibit wide HOMO–LUMO gaps, {high|higher} electron affinity, and {strong|powerful|robust|sturdy} phosphorescence at low temperature.
