1H and 13C spectral assignment of naphtho[2′,1′:5,6]‐naphtho[2′,1′:4,5]thieno[2,3‐c]quinoline using the IDR‐GHSQC‐TOCSY experiment

The assignment of the NMR spectra of the polynuclear heteroaromatic naphtho[2′,1′:5,6]naphtho‐[2′,1′:4,5]thieno[2,3‐c]quinoline is reported. The analysis was based on the homonuclear ROESY, heteronuclear direct GHSQC, IDR‐GHSQC‐TOCSY, and long‐range GHMBC experiments. The complete 1H and 13C shift assignments are reported.
