Optimized geometry of cyanocoronene, C24H11CN, in its principal axis system spanned by the vectors a and b. The highly symmetric coronene has 12 identical carbon sites for CN-substitution that all result in the same cyanocoronene. Its permanent electric dipole moment was calculated to be µa = 5.67 D and µb = 0.59 D. -- astro-ph.GA

Discovery of the 7-ring PAH Cyanocoronene (C24H11CN) in GOTHAM Observations of TMC-1

by Keith CowingApril 10, 2025September 18, 2025

We present the synthesis and laboratory rotational spectroscopy of the 7-ring polycyclic aromatic hydrocarbon (PAH) cyanocoronene (C24H11CN) using a laser-ablation assisted cavity-enhanced Fourier transform microwave spectrometer.
